1. WIN represents the MUTE programming bit pair D6, D5 for the zero crossing window threshold

2. Internal pullup resistor to Vs/2; "LOW" = softmute active

The ANGND and DIGGND layout wires must be kept separated. A 50Ω resistor is

recommended to be put as far as possible from the device.

The CLD - and CDR - can be short-circuited in applications providing 3 wires CD signal
