Microsemi Corporation ZL30130GGG2

Description
The Microsemi ZL30130OC12/STM4 is a Stratum 2/3/3E System Synchronizer/SETS that supports the requirements of ITUT G.8262 for synchronous Ethernet Equipment slave Clocks (EEC option 1 and 2), Telcordia GR1244 Stratum 2/3/3E and GR253, ITUT G.812, G.813, and G.781 SETS. It meets the SONET/SDH jitter generation requirements up to OC12/STM4 and 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).

Features
Supports ITUT G.8262 for synchronous Ethernet Equipment slave Clocks (EEC option 1 and 2)
Supports Telcordia GR1244 Stratum 2/3/3E and GR253, ITUT G.812, G.813, and G.781 SETS
Meets SONET/SDH jitter generation requirements up to OC12/STM4
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, 64 kHz 8 kHz 400 Hz)
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 mode of operation (freerun, locked, holdover)
Flexible input reference monitoring automatically disqualifies references based on frequency and phase irregularities
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) for synchronizing Gigabit Ethernet PHYs
Programmable output synthesizers (P0, P1) generate telecom clock frequencies from any multiple of 8 kHz up to 100 MHz
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
