XRT85L61 BITS (Building Integrated Timing Supply) Clock Extractor

The XRT85L61 is an integrated E1, T1, 64KHz Centralized Clock interface for T1 (1.544Mbps) 100Ω, E1 (2.048Mbps) 75Ω or 120Ω applications. The XRT85L61 extracts either 2048kHz or 1544 kHz clock signals from an E1 (2.048MHz), T1 (1.544MHz) inputs respectively or 64kHz, 8kHz or 400kHz clock signals from the 64kHz reference clock input.
