IDT82V2048 OCTAL T1/E1 SHORT HAUL LINE INTERFACE UNIT
INDUSTRIAL TEMPERATURE RANGES
DESCRIPTION
The IDT82V2048 is a single chip, 8-channel T1/E1 short haul PCM
transceiver with a reference clock of 1.544 MHz (T1) or 2.048 MHz (E1).
The IDT82V2048 contains 8 transmitters and 8 receivers.
All the receivers and transmitters can be programmed to work either
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.
A jitter attenuator is integrated in the IDT82V2048 and can be
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.
The IDT82V2048 offers hardware control mode and software control
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 different
operation modes when the host interface is not available to the device.
The IDT82V2048 also provides loopback and JTAG boundary scan
testing functions. Using the integrated monitoring function, the
IDT82V2048 can be configured as a 7-channel transceiver with non-
intrusive protected monitoring points.
The IDT82V2048 can be used for SDH/SONET multiplexers, central
office or PBX, digital access cross connects, digital radio base stations,
remote wireless modules and microwave transmission systems.
