GENERAL DESCRIPTION

FEATURES

ꢀ

8 Complete E1, T1, or J1 Short-Haul Line

Interface Units

The DS26303 is an 8-channel short-haul line

interface unit (LIU) that supports E1/T1/J1 from a

single 3.3V power supply. A wide variety of

applications are supported through internal

termination or external termination. A single bill of

material can support E1/T1/J1 with minimum external

components. Redundancy is supported through

nonintrusive monitoring, optimal high-impedance

modes, and configurable 1:1 or 1+1 backup

enhancements. An on-chip synthesizer generates the

E1/T1/J1 clock rates by a single master clock input of

various frequencies. Two clock output references are

also offered.
