GENERAL DESCRIPTION
The DS21349 is a fully integrated LIU for long-
haul or short-haul T1 applications over twisted-
pair installations. It interfaces to two twisted-pair
lines—one pair for transmit and one pair for
receive
through
an
interface. The device can be configured for
control through software or hardware mode.
Software control is accomplished over a serial
port, in hardware mode; individual pin settings
allow standalone operation. The device provides
a precise, crystal-less jitter attenuator that can be
placed in either the transmit or receive path.
