NOTES:
1. Exposure to or operating near the Min or Max values for extended period may cause permanent failure and impair reliability of the device.
2. ESD testing method is per MIL-STD-883D,M-3015.7
3. With Linear Air flow of 200 ft/min, reduce Theta JA by 20%, Theta JC is unchanged.
The XRT73R12 is a Twelve-Channel fully integrated Line Interface Unit (LIU) for E3/DS3/STS-1 applications. It incorporates twelve independent Receivers and Transmitters in a single 432 pin TBGA package.
Each channel of the XRT73R12 can be configured to operate in E3 (34.368 MHz), DS3 (44.736 MHz) or STS-1 (51.84 MHz) rates that are independent of each other. Each transmitter can be turned off and tri-stated for redundancy support and power conservation.
The XRT73R12's differential receivers provide high noise interference margin and are able to receive the data over 1000 feet of cable, or with up to 12 dB of cable attenuation.
The XRT73R12 provides a Parallel Microprocessor Interface for programming and control.
The XRT73R12 supports local, remote and digital loop-backs. The XRT73R12 also contains an on-board Pseudo Random Binary Sequence (PRBS) generator and detector with the ability to insert and detect single bit error.
