Description
The ZL30143 is a highly integrated system synchronizer and SETS device designed for central timing cards in carrier-grade network equipment. It provides all the necessary functions for a central timing card, including input reference monitoring, automatic reference selection, support for external and line timing modes, hitless reference switching, wander and jitter filtering, and master/slave crossover for minimizing phase alignment between redundant timing cards. It also features an independent derived output timing path to support the SETS functionality.
Specifications and features
- Supports ITU-T G.8262 for synchronous Ethernet Equipment slave Clocks
- Supports Telcordia GR-1244 Stratum 3 and GR-253, ITU-T G.813, and G.781 SETS
- Supports ITU-T G.823, G.824, and G.8261 for 2048 kbit/s and 1544 kbit/s interfaces
- Meets SONET/SDH jitter generation requirements up to OC-48/STM-16
- Synchronizes to telecom reference clocks (2 kHz, N*8 kHz up to 77.76 MHz, 155.52 MHz) or Ethernet reference clocks (25 MHz, 50 MHz, 62.5 MHz, 125 MHz)
- Supports composite clock inputs (64 kHz, 64 kHz + 8 kHz, 64 kHz + 8 kHz + 400 Hz)
- Generates standard SONET/SDH clock rates or Ethernet clock rates for synchronizing Gigabit Ethernet PHYs
- Programmable output synthesizers generate telecom clock frequencies from any multiple of 8 kHz up to 100 MHz
- Generates several styles of telecom frame pulses with selectable pulse width, polarity, and frequency
- Provides two DPLLs which are independently configurable through a serial interface
- Flexible input reference monitoring automatically disqualifies references based on frequency and phase irregularities
- Provides automatic reference switching and holdover during loss of reference input
- Supports master/slave configuration and dynamic input to output delay compensation for AdvancedTCA™
- Configurable input to output delay and output to output phase alignment
Application Scenarios
- ITU-T G.8262 System Timing Cards which support 1 GbE and 10 GbE interfaces
- Telcordia GR-253 Carrier Grade SONET/SDH Stratum 3 System Timing Cards
- System Timing Cards which supports ITU-T G.781 SETS (SDH Equipment Timing Source)
