CS61582
Dual T1/E1 Line Interface
Features
General Description
•
•

•
a dual line interface
Dual T1/E1 Line Interface Optimized for
The CS61582 isT1/E1 asynchronous or optimized for
highly-integrated
synchronous
Mutiplexer Applications
multiplexer applications such as SONET and SDH.
Low Power Consumption
(Typically 220mW per Line Interface)
Transmit Driver Performance Monitors
Jitter Attenuation in the Transmit Path
Matched Impedance Transmit Drivers
Supports JTAG Boundary Scan
Hardware Mode Derivative of the CS61584
Each channel features individual control and status
pins which eliminates the need for external microproc-
essor support. The matched impedance drivers reduce
power consumption and provide substantial return loss
to insure superior T1/E1 pulse quality.
The CS61582 provides two transmitter driver perform-
ance monitor circuits and JTAG boundary scan to
enhance system testability and reliability. The CS61582
is a 5 volt device that is a hardware mode derivative of
the CS61584.
