digital audio interface output
ground connection for the digital section
not connected
crystal input at 256fs (8.192 MHz)
crystal output at 256fs (8.192 MHz)
serial data input at 728 kbits/s from DQPSK demodulator
output clock at 728 kHz to DQPSK demodulator
active LOW reset; used to set the device in a valid initial condition
clock input for I
data port for I
output mirroring the I
not connected
I
slave addresses, defaults to logic 1
active LOW mute input; when set LOW, sets the digital data to zero and either
silences the output or switches it to analog FM, depending on the status of
MUTEDEF (control bit in the I
(if automute is used, then MUTE is automatically pulled LOW)
not connected
analog supply voltage for the right audio channel
analog ground connection for the right audio channel
internal reference voltage buffer output
internal reference voltage buffer HIGH impedance node
not connected
analog output from the right audio channel
external analog input to the right audio channel
FM sound input to the right audio channel
integrator output from the right audio channel
integrator connection to an external damping capacitor
not connected
reference voltage input; 2.5 V (typical)
