PIN DESCRIPTION

FEATURES

CꢀComplete E1, T1, or J1 line interface unit

(LIU)

CꢀSupports both long- and short-haul trunks

CꢀInternal software-selectable receive-side

termination for 75Ω/100Ω/120ꢀ

Cꢀ5V power supply

44 TQFP

Cꢀ32-bit or 128-bit crystal-less jitter attenuator

requires only a 2.048MHz master clock for

both E1 and T1 with option to use 1.544MHz

for T1

CꢀGenerates the appropriate line build outs,

with and without return loss, for E1 and

DSX-1 and CSU line build outs for T1

CꢀAMI, HDB3, and B8ZS, encoding/decoding

Cꢀ16.384MHz, 8.192MHz, 4.096MHz, or

2.048MHz clock output synthesized to

recovered clock

7mm

CABGA

CꢀProgrammable monitor mode for receiver

CꢀLoopbacks and PRBS pattern generation/

detection with output for received errors

CꢀGenerates/detects in-band loop codes, 1 to 16

bits including CSU loop codes
