Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to the absolute maximum rating conditions for extended periods may affect device.

The DS21349 is a fully integrated LIU for longhaul or short-haul T1 applications over twistedpair installations. It interfaces to two twisted-pair lines-one pair for transmit and one pair forreceive 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.
