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.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 (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, 64kHz + 8 kHz + 400 Hz)
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 synthesizers (P0, P1)
generate 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
Provides two DPLLs which are independently
configurable through a serial interface
