Clarification regarding TLCAD50C codec. - Santosh M Nadig - Sep 28 7:03:00 2001

Hello, 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, Santosh ************************** Santosh M Nadig, Systems Engineer, Accord Software and Systems. PH: 5350105 ************************** |
