XRT8001 - WAN Clock for T1 and E1 Systems

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 preprogrammed multipliers and dividers that are selected via the serial port.

Features

  • Generates Output Clock Frequencies Ranging.
  • From 8kHz up to 16.384MHz Serial Port Control for Optimal Performance Sync Output: 8kHz or 64kHz Low Jitter Cascadable (Master / Slave Modes) No External Components Needed Pin Compatible with the XRT8000 Low Power (3.3V or 5V): 40 - 100mW - 40°C to +85°C Temperature Range 18-Lead PDIP or SOIC Packages.

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 preprogrammed multipliers and dividers that are selected via the serial port. It generates two integer multiples of 8kHz, 56kHz, and 64kHz while locked onto an incoming reference of 1.54MHz (T1), 2.048MHz (E1), 8kHz, 56kHz, or 64kHz The XRT8001 WAN Clock can be configured to operate in one of six modes: 1. The Forward/Master Mode 2. The Reverse/Master Mode 3. The “Fractional T1/E1" Reverse/Master Mode 4. The “E1 to T1 - Forward/Master" Mode 5. The “High Speed - Reverse" Mode 6.
