ASAHI KASEI
Two kinds of data formats can be chosen with the DIF pin (Table 4). In both modes, the serial data is in MSB first, 2’s
complement 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 scales with sampling rate (fs).
HPF is controlled by CKS2-0 pins (Table 3). If HPF setting (ON/OFF) is changed at operating, click noise occurs by
changing DC offset. It is recommended that HPF setting is changed at PDN pin = “L”.
