Rev 2.1 Line Card Protection Switch for SONET or SDH Network Elements

The ACS8515 is a highly integrated, single-chip solution for ‘hit-less’ protection switching of SEC clocks from Master and Slave SETS clockcards in a SONET or SDH Network Element. The ACS8515 has fast activity monitors on the inputs and will implement automatic system protection switching against master clock failure.

Features


  • Suitable for Stratum 3, 4E and 4 SONET or SDH Equipment Clock (SEC) applications
  • Meets AT&T, ITU-T, ETSI and Telcordia (Bellcore) specifications
  • Three SEC input clocks, from 2 kHz to 155.52 MHz
  • Generates two SEC output clocks, up to 311.04 MHz
  • Frequency translation of SEC input clock to a different local line card clock
  • Robust input clock source frequency and activity monitoring on all inputs
  • Supports free-run, locked and holdover modes of operation
  • Automatic 'hit-less' source switchover on loss of input
  • External force fast switch between SEC inputs
  • Phase build out for output clock phase continuity during input switchover
  • SPI™-compatible serial microprocessor interface
  • Programmable wander and jitter tracking attenuation 0.1 Hz to 20 Hz
  • Single +3.3 V operation. +5 V I/O compatible
  • Operating temperature (ambient) -40°C to +85°C
  • 64-pin LQFP package
