DPLL
SyncE/SONET/SDH G.8262/Stratum3
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)
Programmable output synthesizers (P0, P1)
generate telecom clock frequencies from any
multiple of 8 kHz up to 100 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
