GENERAL DESCRIPTION

The XR-T5684 is a fully integrated PCM line transceiver

intended for DSX-1 digital cross-connect applications. It

combines both transmit and receive circuitry in a 28 pin

PLCC or PDIP package. The receiver extracts data from

AMI coded input signal, and outputs synchronized clock and

unipolar RPOS and RNEG data by means of an external 8X

or 16X oversampling clock. The oversampling clock is

necessary only for applications where the clock recovery

feature is required. The transmitter of the device pre-shapes

the transmit pulse internally, providing the appropriate pulse

shape at the cross-connect for line lengths ranging from 0 to

655 feet. The XR-T5684 is manufactured using advanced

CMOS technology and requires only a single +5V power

supply.
