CS61583
OVERVIEW
The CS61583 is a dual line interface for T1/E1
applications, designed for high-volume cards
where low power and high density are required.
One board design can support all T1/E1 short-
haul modes by only changing component values
in the receive and transmit paths (if REFCLK
and TCLK are externally tied together). Figure 5
illustrates applications of the CS61583 in various
environments.
All control of the device is achieved via external
pins, eliminating the need for microprocessor
support. The following pin control options are
available on a per channel basis: line length se-
lection, coder mode, jitter attenuator location,
transmit all ones, local loopback, and remote
loopback.
The line driver generates waveforms compatible
with E1 (CCITT G.703), T1 short haul (DSX-1),
and T1 FCC Part 68 Option A (DS1). A single
transformer turns ratio is used for all waveform
types. The driver internally matches the imped-
ance of the load, providing excellent return loss
to insure superior T1/E1 pulse quality. An addi-
