Clarification regarding TLCAD50C codec.

Started by Santosh M Nadig September 28, 2001

I am using 5402 EVM in which the TLCAD50C codec is interfaced with 5402's
serial port. The codec data sheet specifies that a single pole RC filter
(anti - aliasing)to be used before the INM and INP pins (analog Input).The
RC filter that they have provided has a cut-off of 16KHz. The codec data
sheet says that the "Cutoff can be 4Xfs".
Could anyone tell me what should be the cutoff frequency for a sampling
rate of 8 KHz.

Thanks in adv,
