XRT85L61
XRT85L61 is BITS (BUILDING INTEGRATED TIMING SUPPLY) CLOCK EXTRACTOR manufactured by Exar.
DESCRIPTION
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 2048k Hz or 1544 k Hz clock signals from an E1 (2.048 MHz), T1 (1.544 Mhz) inputs respectively or 64 KHz, 8k Hz or 400 Hz clock signals from the 64k Hz reference clock input.
The XRT85L61 includes an on-chip crystal-less jitter attenuator with 32 bit FIFO that can either be enabled or disabled.
