ZL30130
OC-12/STM-4 SONET/SDH/GbE Stratum 2/3/3E System Synchronizer/SETS
Overview
The ZL30130 SONET/SDH/GbE Stratum 2/3E/3 System Synchronizer and SETS device is a highly integrated device that provides all of the functionality that is required for a central timing card in carrier grade network equipment. |
Simplified Block Diagram

Typical Applications
- ITU-T G.8262 System Timing Cards which support 1GbE interfaces
- Telcordia GR-253 Carrier Grade SONET/SDH Stratum 2/3E/3 System Timing Cards
- System Timing Cards which supports ITU-T G.781 SETS (SDH Equipment Timing Source)
Features & Benefits
- Supports the requirements of ITU-T G.8262 for synchronous Ethernet Equipment slave Clocks (EEC option 1 and 2)
- Supports the requirements of Telcordia GR-1244 Stratum 2/3/3E and GR-253, ITU-T G.812, G.813, and G.781 SETS
- Synchronizes to telecom reference clocks (2 kHz, N*8 kHz up to 77.76 MHz, 155.52 MHz) or to Ethernet reference clocks (25 MHz, 50 MHz, 62.5 MHz, 125 MHz)
- Generates standard SONET/SDH clock rates (e.g. 19.44 MHz, 38.88 MHz, 77.76 MHz, 155.52 MHz, 622.08 MHz) or Ethernet clock rates (e.g. 25 MHz, 50 MHz, 125 MHz) for synchronizing Gigabit Ethernet PHYs
- Programmable output synthesizers (P0, P1) generate telecom clock frequencies from any multiple of 8 kHz up to 100 MHz
