ZL30121GGG2V2 - Brand New Microchip Technology Clock / Timing - Application Specific
-
Description
The ZL30121GGG2V2 is a highly integrated system synchronizer and SETS device specifically designed for use in carrier-grade network equipment. It provides all the necessary functionality for a central timing card, including input reference monitoring, automatic reference selection, support for external timing 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 for the support of SETS functionality.
Specifications and features
- 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 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 the 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 to Ethernet reference clocks (25 MHz, 50 MHz, 62.5 MHz, 125 MHz)
- Supports composite clock inputs (64 kHz, 64 kHz + 8 kHz, 64kHz + 8 kHz + 400 Hz)
- 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, 156.25 MHz, 312.5 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
- 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
- Internal state machine automatically controls the mode of operation (free-run, locked, holdover)
- Flexible input reference monitoring automatically disqualifies references based on frequency and phase irregularities
- Provides automatic reference switching and holdover during the 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 support ITU-T G.781 SETS (SDH Equipment Timing Source)
