Description

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.

An evaluation kit is available:  DS26303DK
