The 82P33813 Synchronization Management Unit (SMU) provides tools to manage timing references, clock sources and timing paths for IEEE 1588 / Precision Time Protocol (PTP) and Synchronous Ethernet (SyncE) based clocks. The device supports up to three independent timing paths that control: PTP clock synthesis; SyncE clock generation; and general purpose frequency translation. The device supports physical layer timing with Digital PLLs (DPLLs) and it supports packet based timing with Digitally Controlled Oscillators (DCOs). Input-to- input, input-to-output and output-tooutput phase skew can all be precisely managed. The device outputs low-jitter clocks that can directly synchronize lower-rate Ethernet interfaces; as well as CPRI/OBSAI, SONET/SDH and PDH interfaces and IEEE 1588 Time Stamp Units (TSUs).

特性

  • SMU allows any IEEE 1588 software, running on an external processor, to control the generation of electical clocks, and to access and control physical layer synchronization
  • Supports Telecom Boundary Clock (T-BC) and Telecom Time Slave Clock (T-TSC) applications per G.8273.2 with physical layer frequency support to the DCOs
  • Physical layer clocks comply with ITU-T G.8262 for Synchronous Ethernet Equipment Clock (EEC), and G.813 for Synchronous Equipment Clock (SEC), and Telcordia GR-253-CORE for Stratum 3 and SONET Minimum Clock (SMC)
  • System-wide precise 1PPS (Pulse Per Second) edge alignment is supported with programmable input-to-input, input-to-output and output-to-output phase delays: sub-ns resolution
  • 24 hour time holdover is supported by DCOs with fine frequency resolution (1.7e-16);Generates clocks for: Ethernet, SONET/SDH and PDH interfaces: jitter generation <1 ps RMS (12 kHz to 20 MHz)
  • IEEE 1588 grand master applications are supported by locking to 1 PPS (Pulse Per Second) references from GPS or other GNSS sources
  • Eases local oscillator sourcing by supporting any of eight common TCXO/OCXO frequencies for the System Clock: 10 MHz, 12.8 MHz, 13 MHz, 19.44 MHz, 20 MHz, 24.576 MHz, 25 MHz or 30.72 MHz
  • Automatically loads configuration from an external EPROM after reset without processor intervention
  • 72 pin QFN package
