ZL30142 SyncE SONET/SDH G.8262/Stratum 3 System Synchronizer Short Form Data Sheet
●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.812, G.813
■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)
■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 synthesizer generates 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
■Internal state machine automatically controls 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 loss of reference input
■ Supports master/slave configuration and dynamic input to output delay compensation for AdvancedTCATM
■Configurable input to output delay and output to output phase alignment
