Features
• Synchronizes to standard telecom or Ethernet backplane clocks and provides jitter filtered output clocks for SONET/SDH, PDH and Ethernet network interface cards
• Supports the requirements of ITU-T G.8262 for synchronous Ethernet Equipment slave Clocks (EEC option 1 and 2)
• Two independent DPLLs provides timing for the transmit path (backplane to line rate) and the receive path (recovered line rate to backplane)
• 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)
• Selectable loop bandwidth of 14 Hz, 28 Hz, 890 Hz, or 0.1 Hz
• Supports automatic hitless reference switching and short term holdover during loss of reference inputs
• Generates standard SONET/SDH clock rates (e.g.
