8A34013E-000NBG#

Meet the 8A34013 Line Card Synchronizer for IEEE 1588 – the ultimate solution for generating and distributing ultra-low jitter timing signals in your system. This state-of-the-art device ensures that Time Stamp Units and SyncE ports across line cards or daughter cards are perfectly synchronized with IEEE 1588 and SyncE references from other sources. Equipped with digital PLLs for seamless reference switching and advanced clock delay measurement capabilities, this synchronizer delivers accurate time and phase synchronization without compromising precision. Offering multiple independent timing channels for clock synthesis, generation, jitter attenuation, and frequency translation, it effectively manages phase skew between inputs and outputs. Its ultra-low-jitter clocks are designed to synchronize high-speed SERDES, CPRI/OBSAI, SONET/SDH, PDH interfaces, and IEEE 1588 TSUs with unparalleled efficiency

Key Features

• Four 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
