Si5348/83/84 Network Synchronizer Clocks

Silicon Labs’ network synchronizer clocks lead the industry in jitter performance,
while offering low power consumption. With up to three integrated DSPLLs and
small package sizes, these devices reduce complexity and PCB footprint
requirements for timing synchronization. Silicon Labs’ network synchronizer
clocks are ideally suited for SyncE/SONET/SDH timing card and pizza box
applications, as well as wireless communication systems and data center
switches. Each DSPLL is individually configurable as a SyncE/SONET/SDH PLL,
IEEE 1588 DCO with support for 1PPS/1Hz, or a general-purpose PLL for processor
or FPGA clocking. Legacy SETS systems can also use these devices to achieve
Stratum 3/3E compliance.



Features

  • Up to three independent DSPLLs support flexible SyncE/SONET/SDH, IEEE 1588 and SETS architectures
  • Each DSPLL generates any output frequency from any input frequency
  • Support for 1PPS/1Hz input and output frequencies
  • Excellent jitter performance of 100 fs RMS
  • Programmable loop bandwidth per DSPLL as low as 0.001Hz
  • Synchronous, free-run and holdover modes
  • Automatic/manual hitless switching
  • Status monitoring: LOL, LOS, OOF
  • Pin or software controllable DCO on each DSPLL with resolution to 1ppt/step
  • Meets the requirements of:
    • ITU-T G.8262 (SyncE) EEC Options 1 & 2
    • ITU-T G.812 Type III, IV
    • ITU-T G.813 Option 1
    • Telcordia GR-1244, GR-253 (Stratum 3/3E)
  • Suitable for ITU-T G.8273.2 applications
