SyncE SONET/SDH
G.8262/Stratum3 System Synchronizer/SETS
Short Form Data Sheet
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

-40oC to +85oC
• Internal state machine automatically controls
mode of operation (free-run, locked, holdover)
• Flexible input reference monitoring automatically
disqualifies references based on frequency and
phase irregularities
• Provides automatic reference switching and
holdover during loss of reference input
• Supports master/slave configuration and dynamic
input to output delay compensation for
AdvancedTCATM
• Configurable input to output delay and output to
output phase alignment
Applications
