MxL5007T is a tuner IC designed mostly for digital signals (DVB-T, ATSC), but it can be used for analog reception too. I will show you how I took it out from a receiver so I can use it in my projects. It has a programmable IF output and it can receive anything from 44 to 885 MHz. There is no datasheet for it, but there are Linux drivers.

Looking at the PCB of a SCART DVB-T MPEG2 receiver I found no components I could use. But, a closer look at the tuner which was basically an area of the PCB enclosed in metallic box revealed only a few tracks coming out of the tuner area. Since it's rather easy to interface a tuner to a simple demodulator and build a high quality receiver, I decided to try to cut the original receiver PCB around the tuner and see if I could control and use it in my projects.

Receiver specifications said it can receive 170 to 230 and 470 to 862 MHz. These seem to be software limits, because the product brief sheet claims this IC can receive from 44 to 885 MHz. First of all I had to trace some lines due to the lack of pinout information. Then I cut (really) the PCB and placed the tuner inside a metal box with easy to make connections. I re-used a metal box from a broken TV tuner.

Everything was connected with tiny pieces of thin wire to a small piece of circuit board that held also the pins on the metal case. In the end, my tuner had fewer pins than the original one in the case. In order to see if I got the pinout right and test the reception I had to build a demodulator. The simplest one was an FM detector built around TA2003 IC. With this I should be able to receive broadcast FM stations on 88 to 108 MHz band.

A tuner takes an user chosen piece of the RF spectrum and translates it to a smaller, fixed frequency. After this frequency conversion, the resulting intermediate frequency signal is passed to a demodulator. The problem here is that TV receiving devices usually have the IF center around 36 MHz. An 8 MHz wide piece of the RF spectrum is available for demodulation at this IF. An FM radio demodulator expects a 250 kHz wide IF centered around 10.7 MHz. Knowing this there are three approaches:

I went for the first method and built a double conversion receiver. First conversion takes place inside the tuner and the second one at the mixer of TA2003. This is actually called double superheterodyne receiver. Second approach requires impossible to find components while the third is an option only when tuner can output an IF closer to standard FM IF.

The practical disadvantage of this double conversion is that you have to build and adjust the local oscillator LC pair. This should be built inside a can (you know those RF can coils inside every radio). Adjustment is done by setting the tuner to a frequency of a radio station and then tuning the coil until you receive it. You will hear neighboring stations while adjusting local oscillator coil, because signals from a piece of 6...8 MHz of the FM band can reach the demodulator. You know you got the right L.O. frequency when you hear what you should hear at the frequency you set the tuner to. Practical build of TA2003 receiver on 36 MHz can be found in this post.

Let's get to the digital part. The tuner is a an I2C slave device. There are no datasheets to describe I2C interface, but the existing Linux drivers for hardware using this tuner provide enough information.

I came up with an Arduino library for MxL5007T. Remember not to connect it to 5V Arduino without level shifter. 5V should not reach MxL5007T on any pin. If your tuner uses a different XTAL frequency than 24 MHz, you need call the init() routine with the correct XTAL frequency. The simplest Arduino sketch using this library could look like this:

The reception quality is very good (if you use proper antenna and turn the AGC potentiometer - R3). IF inversion does not affect the signal unless your detector is not centered on the right IF frequency. ISDB, DVB and ATSC modes don't seem to change anything. Each of the IF outputs can be connected to TA2003 RF input. Do not short them. Do not connect the other to the ground. The frequency step of the tuner is 15.625 kHz, smaller than common TV tuners which have 31.25 kHz or 62.5 kHz. Although you pass frequency in Hz, it is rounded to multiples of 15625 Hz. The first theoretical frequency after 44 MHz that MxL5007T can tune to is 44,007,812.5 Hz. You can configure the software to start with 44,007,813 and then increment by 15,625.

A tuner is a subsystem that receives radio frequency (RF) transmissions, such as FM broadcasting, and converts the selected carrier frequency and its associated bandwidth into a fixed frequency that is suitable for further processing, usually because a lower frequency is used on the output. Broadcast FM/AM transmissions usually feed this intermediate frequency (IF) directly into a demodulator that converts the radio signal into audio-frequency signals that can be fed into an amplifier to drive a loudspeaker.

More complex transmissions like PAL/NTSC (TV), DAB (digital radio), DVB-T/DVB-S/DVB-C (digital TV) etc. use a wider frequency bandwidth, often with several subcarriers. These are transmitted inside the receiver as an intermediate frequency (IF). Subcarriers are then processed like real radio transmissions, but the whole bandwidth is sampled with an analog-to-digital converter (A/D) at a rate faster than the Nyquist rate (that is, at least twice the IF frequency).

A tuner can also refer to a radio receiver or standalone audio component that is part of an audio system such as a hi-fi or stereo, to be connected to a separate amplifier. The verb tuning in radio contexts means adjusting the receiver to detect the desired radio signal carrier frequency that a particular radio station uses.

The simplest tuner consists of an inductor and capacitor connected in parallel, where the capacitor or inductor is made to be variable. This creates a resonant circuit which responds to an alternating current at one frequency. Combined with a detector, also known as a demodulator (diode D1 in the circuit), it becomes the simplest radio receiver, often called a crystal set.

Older models would realize manual tuning by means of mechanically operated ganged variable capacitors. Often several sections would be provided on a tuning capacitor, to tune several stages of the receiver in tandem, or to allow switching between different frequency bands. A later method used a potentiometer supplying a variable voltage to varactor diodes in the local oscillator and tank circuits of front end tuner, for electronic tuning.

Modern radio tuners use a superheterodyne receiver with tuning selected by adjustment of the frequency of a local oscillator. This system shifts the radio frequency of interest to a fixed frequency so that it can be tuned with fixed-frequency band-pass filter. Still later, phase locked loop methods were used, with microprocessor control.

In a self-contained radio receiver for audio, the signal from the detector after the tuner is run through a volume control and to an amplifier stage. The amplifier feeds either an internal speaker or headphones. In a tuner component of an audio system (for example, a home high-fidelity system or a public address system in a building), the output of the detector is connected to a separate external system of amplifiers and speakers.

Standalone audio stereo FM tuners are sought after for audiophile and TV/FM DX applications, especially those produced in the 1970s and early 1980s, when performance and manufacturing standards were among the highest.[1] In many instances the tuner may be modified to improve performance. Electronics specialists and hobbyists buy, collect and restore vintage FM or AM/FM audio tuners on the secondary market. The restoration usually begins with replacing the electrolytic capacitors that may age over time. The tuner is outfitted with improved tolerance and better sounding upgraded parts. Prices have increased relative to the increasing demand for the older audio tuners. Those with the most value are the best sounding, most rare (collectible), the best DX capable (distance reception) and the known build quality of the component, as it left the factory.[2]

Most of the early tuner models were designed and manufactured to receive only the AM broadcast band. As FM became more popular, the limitations of AM became more apparent, and FM became the primary listening focus, especially for stereo and music broadcasting.[citation needed]

In Europe, where a second AM broadcast band is used for longwave broadcasting, tuners may be fitted with both the standard medium wave and the additional longwave band. However, radios with only medium wave are also common, especially in countries where there are no longwave broadcasters. Rarely, radios are sold with only FM and longwave, but no medium wave band. Some tuners may also be equipped with one or more short wave bands.

A television tuner converts a radio frequency analog television or digital television transmission into audio and video signals which can be further processed to produce sound and a picture. Different tuners are used for different television standards such as PAL, NTSC, SECAM, ATSC, DVB-C, DVB-T, DVB-T2, ISDB, DTMB, T-DMB, open cable. An example frequency range is 48.25 MHz - 855.25 MHz (E2-E69),[4] with a tuning frequency step size of 31.25, 50 or 62.5 kHz.[4] Modern solid-state internal TV-tuner modules typically weigh around 45 g.[4] 2351a5e196
