■
Two kinds of data formats can be selected by the DIF pin
compliment format. The SDTO is clocked out on the falling edge of SCLK. The audio interface supports both master and
slave modes. In master mode, SCLK and LRCK are output with the SCLK frequency fixed to 64fs and the LRCK
frequency fixed to 1fs.
■
The ADC has a digital high pass filter for DC offset cancellation. The cut-off frequency of the HPF is 1.0Hz
(@fs=48kHz) and it scales with sampling rate (fs).
