IDT82V2048 OCTAL T1/E1 SHORT HAUL LINE INTERFACE UNIT
DESCRIPTION:
transceiver with a reference clock of 1.544MHz (T1) or 2.048MHz (E1).
It contains 8 transmitters and 8 receivers.
either in single rail mode or dual rail mode. AMI or HDB3/B8ZS 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
integrated 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 chan-
PIN CONFIGURATIONS
The IDT82V2048 is a single chip, 8-channel T1/E1 short haul PCM
Both the receivers and transmitters can be programmed to work
A jitter attenuator is integrated in the IDT82V2048 and can be

mode. Software control mode works with either serial host interface or
parallel host interface. The latter works via an Intel/Motorola compatible
8-bit parallel interface for both multiplexed or non-multiplexed applica-
tions. Hardware control mode uses multiplexed pins to select differ-
ent operation modes when the host interface is not available to the
device.

IDT82V2048 can be configured as a 7-channel transceiver with non-in-
trusive protected monitoring points.

remote wireless modules and microwave transmission systems.
The IDT82V2048 offers hardware control mode and software control
The IDT82V2048 also provides loopback and JTAG boundary scan
The IDT82V2048 can be used for SDH/SONET multiplexers, central
