描述
The 8A34003 system synchronizer for IEEE 1588 generates ultra-low jitter; precision timing signals based on the IEEE 1588 Precision Time Protocol (PTP) and Synchronous Ethernet (SyncE). The device can be used as a single timing and synchronization source for a system or two of them can be used as a redundant pair for improved system reliability. Digitally Controlled Oscillators (DCOs) are available to be controlled by IEEE 1588 clock recovery servo software running on an external processor. The device supports physical layer timing with Digital PLLs (DPLLs) and other timing blocks necessary to implement a Synchronous Equipment Timing Source (SETS) for SyncE. The DCOs can be controlled using IEEE 1588 information alone, or they can combine IEEE 1588 time information with physical layer frequency information from SyncE in accordance with ITU-T G.8273.2. 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 Time Stamp Units (TSUs) in a system. The 8A34003 supports multiple independent channels that control 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.
