Abstract

This application note applies to the following devices:

TAC5212, TAC5112, TAC5211, TAC5111, TAA5212, TAD5212, TAD5112, TAC5412-Q1, TAC5411-Q1, TAC5312-Q1, TAC5311-Q1, TAC5212-Q1, TAC5211-Q1, TAC5112-Q1, TAC5111-Q1, TAA5412-Q1, TAD5212-Q1, TAD5112-Q1

The Clock Detection Module in the TAX5X Family comprises of the following functionality:

  • Detecting Sampling Rate (Fs Rate).
  • Detecting Ratio between supplied source Clock and supplied Fsync.
  • Monitoring Fs Rate and Source Clock to Fs Ratio and flag corresponding indications if any change in the value is detected.
  • Registers that record the incoming Fs Rate ans clk to Fs ratio for both.
