Transmit RF Output. This output is an

emitter follower and should be AC

coupled.

I (CMOS) Transmit Data Input. Drives the transmit

VDD

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 XCEN 1

referenced to VDD and VSS.

O (CMOS)

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.
