CS61582
Dual T1/E1 Line Interface
Features
General Description
• Dual T1/E1 Line Interface Optimized for
Mutiplexer Applications
• 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
The CS61582 is a dual line interface optimized for
highly-integrated T1/E1 asynchronous or synchronous
multiplexer applications such as SONET and SDH.
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.
