DS26334

3.3V, 16-Channel, E1/T1/J1 Short-

and Long-Haul Line Interface Unit

www.maxim-ic.com

GENERAL DESCRIPTION

FEATURES

16 E1, T1, or J1 Short/Long-Haul Line

Interface Units

The DS26334 is a 16-channel short/long-haul line

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

single 3.3V power supply. A single bill of material can

support E1/T1/J1 that requires no external

termination. 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. The device is offered in a 256-pin

TE-CSBGA, the smallest package available for a

16-channel LIU.

Independent E1, T1 or J1 Selections
