Data Output. A high impedance three-state digital output for 8 bit wide channel data
being sent to the Layer 1 transceiver. Data is shifted out via this pin concurrent with
the rising edge of the bit clock during the timeslot defined by STB, or according to
standard ST-BUS timing.
Data Input. A digital input for 8 bit wide channel data received from the Layer 1
transceiver. Data is sampled on the falling edge of the bit clock during the timeslot
defined by STB, or according to standard ST-BUS timing. Input level is CMOS
compatible.
timeslot 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.
for the internal device functions. For SSI mode connect the bit clock to this pin when
it is 512 kHz or greater. Connect a 4096 kHz clock to this input when the available bit
clock is 128 kHz or 256 kHz. For ST-BUS mode connect C4i to this pin.
Positive Power Supply (Input). Nominally 3 volts.
(balanced).
Analog Ground (Input). Nominally 0 volts.
Inverting Microphone (Input). Inverting input to microphone amplifier from the
handset microphone.
Non-Inverting Microphone (Input). Non-inverting input to microphone amplifier
from the handset microphone.
No Connect. (DIP Package only).
