MaxLinear, Inc. Interface - Telecom XRT5793IVTR-F

The XRT5793IVTR-F is a quad E1 line interface unit designed for primary rate PCM applications up to 2.048 Mbps. It features four independent channels, each capable of performing driver and receiver functions to convert bipolar signals to TTL/CMOS compatible logic levels. The device supports both single-ended and balanced line interfaces, allowing for flexibility in system design and potential cost savings by using capacitive coupling instead of transformers. This unit includes individual channel loss of signal detection and local/remote loopback capabilities, enhancing its utility in multi-line E1 interface cards and E1 network equipment such as multiplexers and switching systems. The XRT5793IVTR-F is compliant with CCITT G.703 pulse mask specifications and offers a minimum return loss of 20 dB on receive interfaces and 18 dB on transmit interfaces, exceeding relevant ETSI standards. Operating over a temperature range of -40¬8C to +85¬8C, the device is built using low power CMOS technology, making it suitable for applications where power consumption and board space are critical. The part is available in an 80-lead TQFP package, facilitating integration into various telecom systems.
