General Description
The CS61583 is a dual line interface for T1/E1 applica-
tions, designed for high-volume cards where low power
and high density are required. Each channel features
individual control and status pins which eliminates the
need for external microprocessor support. The
matched impedance drivers reduce power consumption
and provide substantial return loss to insure superior
T1/E1 pulse quality.
The CS61583 provides JTAG boundary scan to en-
hance system testability and reliability. The CS61583 is
a 5 volt device and is a hardware mode derivative of
the CS61584.
