GENERAL 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.
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
