ACS8510 Datasheet | SEMTECH

ADVANCED MUNCIATIONS Description The ACS8510 is a highly integrated, single-chip solution for the Synchronous Equipment Timing Source (SETS) function in a SONET or SDH Network Element. The device generates SONET or SDH Equipment Clocks (SEC) and frame synchronization clocks. The ACS8510 is fully pliant with the required specifications and standards. The device supports Free-Run, Locked and Holdover modes. It also supports all three types of reference clock source: recovered line clock, PDH network, and node synchronization. The ACS8510 generates independent SEC and BITS clocks, an 8 k Hz Frame Synchronization clock and a 2 k Hz Multi-Frame Synchronization clock. Two ACS8510 devices can be used together in a Master/Slave configuration mode allowing system protection against a single ACS8510 failure. A microprocessor port is incorporated, providing access to the configuration and status registers for device setup and monitoring. The ACS8510 supports IEEE 1149.1 JTAG boundary scan. - Meets Holdover requirements, lowest bandwidth 0.1 Hz.
