XRT85L61
BITS (BUILDING INTEGRATED TIMING SUPPLY) CLOCK EXTRACTOR
OCTOBER 2004
GENERAL 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 2048kHz or 1544 kHz clock signals from an E1 (2.048 MHz), T1 (1.544 Mhz) inputs respectively or 64 KHz, 8kHz or 400 Hz clock signals from the 64kHz reference clock input.
The XRT85L61 includes an on-chip crystal-less jitter attenuator with 32 bit FIFO that can either be enabled or disabled.
FEATURES
• Fully integrated single chip solution for E1,T1 or 64
kHz clock synchronization applications.
