MaxLinear, Inc. Interface - Telecom XRT5793IV-F

The XR-T5793IV is a quad E1 line interface unit designed for primary rate PCM applications up to 2.048Mbps. 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 cost reduction by potentially eliminating transformers. Key specifications include a minimum return loss of 20dB on receive interfaces and 18dB on transmit interfaces, exceeding G.703 and ETSI 300 166 standards. The device incorporates individual channel loss of signal detection and supports local and remote loopbacks for enhanced diagnostics. It operates within a temperature range of -40¬8C to +85¬8C and is available in an 80-lead TQFP package. The XR-T5793 is suitable for multi-line E1 interface cards, multiplexers, cross connects, and fault-tolerant systems, making it a versatile choice for telecom applications.
