Silicon Labs Si570 Manhattan breakout board

When I got into software defined radio (SDR), I quickly learned about the Silicon Labs Si570 and how it was a small revolution in clock generation for homebrew radios. I was able to quickly obtain some samples from Silicon Labs. Given that the Si570 is a surface mount device, I needed to develop a breakout board to mount the device. That way I could easily solder the device into any radio circuit. I was developing my Software Defined Hardware Radio, so I needed a breakout board that lent itself to Manhattan-style construction.

I used EagleCAD to create a small breakout board using an Si570 package definition someone had already developed. Adobe PDFs of the schematic and board layout are provided at the end of this web page. Below are photos of the finished breakout board (tinned, but otherwise bare) and a populated breakout board as it was used in my Software Defined Hardware Radio. The two 2N7000 FETs (just below the breakout board) were used to provide logic level translation between the Si570 (3.3 Volts) and the Cypress CY8C29466 PSoC (5 volts).
