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.
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.
APPLICATIONS
T1 Digital Cross-Connects
ATM and Frame Relay Equipment
Wireless Base Stations
ISDN Primary Rate Interface
E1/T1/J1 Multiplexer and Channel Banks
E1/T1/J1 LAN/WAN Routers
