GGGAA - Brand New STMicroelectronics IC Chips
-
Description
The GGGAA is a highly integrated electronic component model that serves as a central timing card in carrier grade network equipment. It provides various functions including input reference monitoring, automatic reference selection, support for external and line timing modes, hitless reference switching, wander and jitter filtering, master/slave crossover, and independent derived output timing path for SETS functionality.
Specifications and features
- Supports ITU-T G.8262 for synchronous Ethernet Equipment slave Clocks (EEC option 1 and 2)
- 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 the SONET/SDH jitter generation requirements up to OC-48/STM-16
- Synchronizes to telecom reference clocks or Ethernet reference clocks
- Supports composite clock inputs
- Generates standard SONET/SDH clock rates or Ethernet clock rates for synchronizing Gigabit Ethernet PHYs
- Programmable output synthesizers generate telecom clock frequencies
- Generates several styles of telecom frame pulses
- Provides two independently configurable DPLLs
- Internal state machine automatically controls mode of operation
- Flexible input reference monitoring
- Automatic reference switching and holdover during loss of reference input
- Supports master/slave configuration and dynamic input to output delay compensation
- Configurable input to output delay and output to output phase alignment
Application Scenarios
The GGGAA is commonly used in ITU-T G.8262 System Timing Cards, Telcordia GR-253 Carrier Grade SONET/SDH Stratum 3 System Timing Cards, and System Timing Cards that support ITU-T G.781 SETS.
