* ALSA driver for ICEnsemble VT1724 (Envy24HT)
|
|
|
|
*
|
|
|
|
* Lowlevel functions for AudioTrak Prodigy 192 cards
|
2007-04-10 17:39:58 +08:00
|
|
|
* 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)
|
2007-04-24 18:27:36 +08:00
|
|
|
* - 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
|
2020-08-06 10:19:26 +08:00
|
|
|
* sampling rate. That means that the FPGA doubles the
|
2007-04-24 18:27:36 +08:00
|
|
|
* MCK01 rate.
