DS2149规格书详情
GENERAL DESCRIPTION
The DS2149 is a fully integrated LIU for long haul or short-haul T1 applications over twisted
pair installations. It interfaces to two twisted-pair linesóone pair for transmit and one pair for
receive through an appropriate network 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.
