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
with
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. The device is offered in a 256-pin
TEBGA, the smallest package available for a 16-
channel LIU.
