STA308

18/33

The STA308 features a DDX processing mode that minimizes the amount of noise generated in frequency range

of AM radio. This mode is intended to be used when DDX is operating in a device with an AM tuner active. The

SNR of the DDX processing is reduced to ~83dB in this mode, which is still greater than the SNR of AM radio.

This output bit, on pin 51 of the device, is used to mute the DDX Power Devices for Power-Down.
