Transmit RF Output. This output is an
emitter follower and should be AC
coupled.
Transmit Data Input. Drives the transmit
pulse shaping circuits. Serial digital data
on this pin becomes FSK modulation on
the Transmit RF output. The logic timing
on this pin controls data timing. Internal
circuits determine the modulation
deviation. This is a standard CMOS input
referenced to VDD and VSS.
Serial digital output after demodulation,
chip rate filtering and center data slicing.
A CMOS level output (VSS to VDD) with
controlled slew rates. A low drive output
designed to drive a PCB trace and a
CMOS logic input while generating
minimal RFI. In digital test modes this pin
becomes a test access port controlled by
the serial control bus.
