ZL30145
SyncE (10 GbE) SONET/SDH Rate
Conversion and Jitter Attenuator PLL
Short Form Data Sheet
Features
• Can be used in systems to support the
requirements of ITU-T G.8262 for synchronous
Ethernet Equipment slave Clocks (EEC option 1
and 2)
• Meets jitter generation requirements of Telcordia
GR-253-CORE for OC-192, OC-48, OC-12 and
OC-3 rates
• Meets jitter generation requirements of ITU-T G.813
for STM-64, STM-16, STM-4 and STM-1 rates
• Synchronizes to standard telecom or Ethernet clock
and provides jitter filtered output clock for
SONET/SDH and Synchronous Ethernet line cards
• 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 Ethernet PHYs
• Selectable loop bandwidth of 14 Hz, 28 Hz, or
890 Hz
