XRT8001
WAN Clock for T1 and E1 Systems
October 2001-1
GENERAL DESCRIPTION
The XRT8001 WAN Clock is a dual-phase-locked loop
chip that generates two very low jitter output clock
signals that can be used for synchronization clocks in
wide area networking systems. The XRT8001 has pre-
programmed multipliers and dividers that are selected
via the serial port. It generates two integer multiples of
8kHz, 56kHz, and 64kHz while locked onto an incom-
ing reference of 1.54MHz (T1), 2.048MHz (E1), 8kHz,
56kHz, or 64kHz
The XRT8001 WAN Clock can be configured to oper-
ate in one of six modes:
1. The Forward/Master Mode
2. The Reverse/Master Mode
3. The 鈥淔ractional T1/E1" Reverse/Master Mode
4. The 鈥淓1 to T1 - Forward/Master" Mode
5. The 鈥淗igh Speed - Reverse" Mode
6. The 鈥淪lave鈥?Mode
