* ALSA driver for ICEnsemble VT1724 (Envy24HT) |
|
* |
|
* Lowlevel functions for AudioTrak Prodigy 192 cards |
|
* Supported IEC958 input from optional MI/ODI/O add-on card. |
|
* |
|
* Specifics (SW, HW): |
|
* ------------------- |
|
* * 49.5MHz crystal |
|
* * SPDIF-OUT on the card: |
|
* - coax (through isolation transformer)/toslink supplied by |
|
* 74HC04 gates - 3 in parallel |
|
* - output switched between on-board CD drive dig-out connector |
|
* and ice1724 SPDTX pin, using 74HC02 NOR gates, controlled |
|
* by GPIO20 (0 = CD dig-out, 1 = SPDTX) |
|
* * SPDTX goes straight to MI/ODI/O card's SPDIF-OUT coax |
|
* |
|
* * MI/ODI/O card: AK4114 based, used for iec958 input only |
|
* - toslink input -> RX0 |
|
* - coax input -> RX1 |
|
* - 4wire protocol: |
|
* AK4114 ICE1724 |
|
* ------------------------------ |
|
* CDTO (pin 32) -- GPIO11 pin 86 |
|
* CDTI (pin 33) -- GPIO10 pin 77 |
|
* CCLK (pin 34) -- GPIO9 pin 76 |
|
* CSN (pin 35) -- GPIO8 pin 75 |
|
* - output data Mode 7 (24bit, I2S, slave) |
|
* - both MCKO1 and MCKO2 of ak4114 are fed to FPGA, which |
|
* outputs master clock to SPMCLKIN of ice1724. |
|
* Experimentally I found out that only a combination of |
|
* OCKS0=1, OCKS1=1 (128fs, 64fs output) and ice1724 - |
|
* VT1724_MT_I2S_MCLK_128X=0 (256fs input) yields correct |
|
* sampling rate. That means that the FPGA doubles the |
|
* MCK01 rate. |
