ZL30402 SONET/SDH Network Element PLL
| Product Status - Production |
|
The ZL30402 is a Network Element Phase-Locked Loop designed to synchronize SDH and SONET systems. In addition, it generates multiple clocks for legacy PDH equipment and provides timing for ST-BUS and GCI backplanes.
Features
- Meets requirements of GR-253 for SONET stratum 3 and SONET Minimum Clocks (SMC)
- Meets requirements of GR-1244 for stratum 3
- Meets requirements of G.813 Option 1 and 2 for SDH Equipment Clocks (SEC)
- Generates clocks for ST-BUS, DS1, DS2, DS3, OC-3, E1, E2, E3, STM-1 and 19.44 MHz
- Maintains Holdover accuracy to 1x10 -12
- Continuously monitors Primary and Secondary reference clocks
- Provides "hit-less" reference switching
- Compensates for Master Clock Oscillator accuracy
- Detects frequency of both reference clocks and synchronizes to any combination of 8 kHz, 1.544 MHz, 2.048 MHz and 19.44 MHz reference frequencies
- Allows Hardware or Microprocessor control
- Pin compatible with MT90401 device
Typical Applications
-
Synchronization for SDH and SONET Network Elements
- Clock generation for ST-BUS and GCI backplanes
