XRT85L61 Bits (Building Integrated Timing Supply) Clock
Extractor
General Description:
The XRT85L61 is an integrated E1, T1, 64KHz Centralized Clock
interface for T1 (1.544Mbps) 100 ,E1 (2.048Mbps) 75 or
120 applications.
The XRT85L61 extracts either 2048kHz or 1544 kHz clock signals from an
E1 (2.048 MHz), T1 (1.544Mhz) 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.
Key Features:
Fully integrated single chip solution for E1,T1
or 64
kHz clock synchronization applications.
