Hi Sir,
AIC3254 EVM how to settting 192K I2S input in master mode
Hi,
Please take a look at the following script. It is an example of how to configure the codec for a 192ksps in master mode:
############################################## # High Performance Stereo Recording # --------------------------------------------- # PowerTune mode PTM_R4 is used for high # performance 16-bit audio. # # For normal USB Audio, no hardware change # is required. # # If using an external interface, SW2.4 and # SW2.5 of the USB-ModEVM must be set to # HI and clocks can be connected to J14 of # the USB-ModEVM. # # IN1L/R is routed to the LADC/RADC in a # single-ended manner. ############################################### ############################################### # Software Reset ############################################### # # Select Page 0 w 30 00 00 # # Initialize the device through software reset w 30 01 01 # ############################################### ############################################### # Clock Settings # --------------------------------------------- # The codec receives: MCLK = 11.2896 MHz # BLCK = 6.144 MHz, WCLK = 192 kHz ############################################### # # Clock configuration w 30 00 00 w 30 04 03 w 30 05 12 w 30 06 28 w 30 05 F2 w 30 12 87 w 30 13 83 w 30 14 20 w 30 1D 03 w 30 1E 81 w 30 1B 0C w 30 21 10 # ############################################### ############################################### # Signal Processing Settings ############################################### # # Select Page 0 w 30 00 00 # # Set the ADC Mode to PRB_P1 w 30 3d 0d # ############################################### ############################################### # Initialize Codec ############################################### # # Select Page 1 w 30 00 01 # # Disable weak AVDD in presence of external # AVDD supply w 30 01 08 # # Enable Master Analog Power Control w 30 02 00 # # Select ADC PTM_R4 w 30 3d 00 # # Set the input powerup time to 3.1ms (for ADC) w 30 47 32 # # Set the REF charging time to 40ms w 30 7b 01 # ############################################### ############################################### # Recording Setup ############################################### # # Select Page 1 w 30 00 01 # # Route IN1L to LEFT_P with 20K input impedance w 30 34 80 # # Route Common Mode to LEFT_M with impedance of 20K w 30 36 80 # # Route IN1R to RIGHT_P with input impedance of 20K w 30 37 80 # # Route Common Mode to RIGHT_M with impedance of 20K w 30 39 80 # # Unmute Left MICPGA, Gain selection of 6dB to make channel gain 0dB # Register of 6dB with input impedance of 20K => Channel Gain of 0dB w 30 3b 0c # # Unmute Right MICPGA, Gain selection of 6dB to make channel gain 0dB # Register of 6dB with input impedance of 20K => Channel Gain of 0dB w 30 3c 0c # # Select Page 0 w 30 00 00 # # Power up LADC/RADC w 30 51 c0 # # Unmute LADC/RADC w 30 52 00 # ###############################################
The USB I2S switch (SW2 on MODEVM-INTERFACE BOARD) must be disabled in order to use the codec in master mode.

Dear Sir,
If we want to analog in/out with EQ setting, we also need provide MCLK/BCLK/LRCLK? or MCLK only?
