Exar Corporation XRT5997
The XRT5997 is an optimized seven-channel analog E1 line interface unit fabricated using low power 3.3V CMOS technology. Each channel consists of both a Transmitter and a Receiver function. The Transmitter accepts a TTL or CMOS level signal from the Terminal Equipment; and outputs this data to the line via bipolar pulses that are compliant to the ITU-T G.703 pulse template for E1.| Part No. | XRT5997 |
