used by the device for both transmit and receive data. This active high signal has a
repetition rate of 8 kHz. Standard frame pulse definitions apply in ST-BUS mode. CMOS
level compatible input.
BUS mode this is the C4i input. In SSI synchronous mode, this is the Bit Clock input. In
SSI-asynchronous mode this is an asynchronous 4 MHz Master Clock input.
Crystal Input (4.096 MHz). Used in conjunction with the CLOCKin pin to provide the master
clock signal via external crystal.
Positive Power Supply (Input). Nominally 5 volts.
Inverting Speaker (Output). Output to the speakerphone speaker (balanced).
Non-Inverting Speaker (Output). Output to the speakerphone speaker (balanced).
Auxiliary Port (Output). Access point to the D/A (analog) signals of the receive path as
well as to the various analog inputs.
Auxiliary Port (Input). An analog signal may be fed to the filter/codec transmit section and
various loopback paths via this pin. No external anti-aliasing is required.
Non-inverting on-hook answer back Microphone (Input). Microphone amplifier non-
inverting input pin.
Analog Ground (Input). Nominally 0 V.
