Case 6: Pro-X FXS
W681308
XXXX PRODUCT DESCRIPTION
Register Setting:
0x1460 = 0x81 (Enable Gain Stage, Link PCM_USB)
0x1470 = 0x80 (Enable PCM)
0x1465 = 0x40 (Mute CODEC D/A OUT)
12.6 I2S Register Setting Example
The following example will generate I2S interface format from the W681308 PCM interface.
I2S for 48KHz Sampling Rate(SR) with 16bits LPCM :
0x1470 = 85
0x1470 [2:0]
101 = BCLK Rate Select. SR x 32 bits = 48K x 32 = 1.536MHz ( L,
R channels are 16 bits format)
0x1470 [4:3]
00 = FST Location, Frame Sync is occurred before the MSB of the
PCM data.
0x1470 [7]
1 = Enable PCM Interface
0x1472
F0 = For long frame
0x14 74
40 = PCM bit clock inverse enable
