9.4.3 Zero Data Detect

The PCM5252 has a zero-detect function. When the device detects the continuous zero data for both left and

right channels, or separate channels, Analog mutes are set to both OUTL and OUTR, or separate OUTL and

OUTR. These are controlled by Page0, Register 65, D(2:1) as shown in Table 5.

Continuous Zero data cycles are counted by LRCK, and the threshold of decision for analog mute can be set by

Page 0, Register 59, D(6:4) for L-ch, and D(2:0) for Rch as shown in Table 6. Default values are 0 for both

channels.
