IDT82V2048S OCTAL T1/E1 SHORT HAUL LIU WITH SINGLE ENDED OPTION
DESCRIPTION
transceiver with a reference clock of 1.544 MHz (T1) or 2.048 MHz (E1).
The IDT82V2048S contains 8 transmitters and 8 receivers.
in Single Rail mode or Dual Rail mode. B8ZS/HDB3 or AMI encoder/
decoder is selectable in Single Rail mode. Pre-encoded transmit data in
NRZ format can be accepted when the device is configured in Dual Rail
mode. The receivers perform clock and data recovery by using inte-
grated digital phase-locked loop. As an option, the raw sliced data (no
retiming) can be output on the receive data pins. Transmit equalization is
implemented with low-impedance output drivers that provide shaped
waveforms to the transformer, guaranteeing template conformance.
switched into either the transmit path or the receive path for all channels.
The jitter attenuation performance meets ETSI CTR12/13, ITU G.736,
G.742, G.823, and AT&T Pub 62411 specifications.
PIN CONFIGURATIONS
The IDT82V2048S is a single chip, 8-channel T1/E1 short haul PCM
All the receivers and transmitters can be programmed to work either
A jitter attenuator is integrated in the IDT82V2048S and can be

control mode. Software control mode works with either serial host inter-
face or parallel host interface. The latter works via an Intel/Motorola
compatible 8-bit parallel interface for both multiplexed or non-multi-
plexed applications. Hardware control mode uses multiplexed pins to
select different operation modes when the host interface is not available
to the device.
testing functions. Using the integrated monitoring function, the
IDT82V2048S can be configured as a 7-channel transceiver with non-
intrusive protected monitoring points.
central office or PBX, digital access cross connects, digital radio base
stations, remote wireless modules and microwave transmission
systems.
The IDT82V2048S offers hardware control mode and software
The IDT82V2048S also provides loopback and JTAG boundary scan
The IDT82V2048S can be used for SDH/SONET multiplexers,
