Datasheet Summary
Data Sheet Twelve Channel E3, DS3, and STS-1
Line Interface Unit with Jitter
General Description
The XRT75R12 is a twelve channel, fully integrated Line Interface Unit (LIU) featuring MaxLinear’s R3 Technology (Reconfigurable, Relayless Redundancy) for E3, DS3, and STS-1 applications. The LIU incorporates 12 independent receivers, transmitters and jitter attenuators in a single 420 lead TBGA package.
Each channel of the XRT75R12 can be independently configured to operate in E3 (34.368MHz), DS3 (44.736MHz) or STS-1 (51.84MHz). Each transmitter can be turned off and tri-stated for redundancy support or for conserving power.
The XRT75R12’s differential receiver provides high noise...
