Other Parts Discussed in Thread: TLV320AIC20, TLV320AIC3104, TLV320AIC3106

are looking for analog codec similar to TLV320AIC20 , dual channel, 16 bit, that can interface to handest, headset and handsfree speaker and mic from the analog side and the TI TNETV1050/1051 in the digital side.

We need sampling frequency of 32KHz.

    Hi Eli,

    Perhaps the TLV320AIC3104 will be a good choice. This Codec supports stereo channel ADC and DAC, 16, 20, 24 or 32 bit data, 8kHz- 96KHz sampling rate and has up to 6 SE or 4 Diff analog inputs. The Audio serial interface supports I2S, Left- and Right-Justified, DSP, and TDM Modes.

    Our DSP is TI  TNETV1051 It does not support I2S

    It support a regular multi channel serial port as common in TI DSPs  (with data , clock and frame sync signals)

    Do you have a codec that can interface to a regular serial port ? Is TLV320AIC3106 is the right solution?

     Any other options?
