The 8A34012 Port Synchronizer for IEEE 1588 regenerates and distributes ultra-low jitter; precision timing signals that are locked to IEEE 1588 and Synchronous Ethernet (SyncE) reference sources elsewhere in a system. The device can be used to precisely synchronize IEEE 1588 Time Stamp Units (TSUs) and SyncE ports on line cards or daughter cards that are connected with synchronization sources across backplanes or other media that introduce clock propagation delays. Digital PLLs (DPLLs) support hitless reference switching between references from redundant timing sources. The device can be used to actively measure and compensate for clock propagation delays across backplanes and across circuit boards to ensure the distribution of accurate time and phase with minimal time error between IEEE 1588 TSUs in a system. The device supports multiple independent timing channels for: IEEE 1588 clock synthesis; SyncE clock generation; jitter attenuation and universal frequency translation.  Input-to-input, input-to-output and output-to-output phase skew can all be precisely managed.  The device outputs ultra-low-jitter clocks that can directly synchronize SERDES running at up to 28Gbps; as well as CPRI/OBSAI, SONET/SDH and PDH interfaces and IEEE 1588 TSUs.

Features

  • Eight independent timing channels
  • Jitter output below 150fs RMS (typical)
  • Digital PLLs (DPLLs) lock to any frequency from 1kHz to 1GHz
  • DPLLs / Digitally Controlled Oscillators (DCOs) generate any frequency from 0.5Hz to 1GHz
  • DCO outputs can be aligned in phase and frequency with the outputs of any DPLL or DCO
  • IEEE 1588 Support:
    • Precise (1ps) resolution for phase measurement and control
    • All outputs/inputs can be configured to decode/encode PWM clock signals
    • PWM can be used to transmit and receive embedded frame and sync pulses; as well as Time of Day (ToD) and other data
  • Reference monitors qualify/disqualify references depending on LOS, activity, frequency monitoring and/or LOS input pins
  • Automatic reference selection state machines select the active reference for each DPLL based on the reference monitors, priority tables, revertive / non-revertive and other programmable settings
  • Device requires a crystal oscillator or fundamental-mode crystal: 25MHz to 54MHz
  • The device can configure itself automatically after reset via:
    • Internal Customer-programmable One-Time Programmable memory 
    • Standard external I2C EPROM via separate I2C Master Port
