USB to 8bit port - FIFO - CPLD - Stereo I2S

November, 2007

I made small board with Generic FIFO + CPLD to generate I2S signal.

(On the Left) 8bit Parallel interface, Cypress FIFO, CPLD, Clock, and buffer.
(On the Right) DAC, and I2S to SPDIF transmitter.
(small green) FT245R board, SparcFun.com

Loopback Test, 1kHz wave - simple WAV player (source attached) - FT245R - this board - CS4394 DAC - Rolland UA1EX.

I used PC and FT245R to supply PCM data into this board, but it's not limited for PC. any MCU which has 8 bit parallel port can supply PCM data into this board.
