DS26334 - E1/T1/J1 Shortand Long-Haul Line Interface Unit

General Description

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.

Key Features

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.
