Rev 2.1 Synchronous Equipment Timing Source for SONET or SDH Network Elements

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.

Features


  • Highly integrated, single-chip solution
  • Suitable for Stratum 3E, 3, 4E and 4 SONET or SDH equipment clock (SEC) applications
  • Meets holdover requirements, lowest bandwidth 0.1 Hz
  • Meets AT&T, ITU-T, ETSI and Telcordia (Bellcore) specifications
  • Accepts 14 individual input reference clocks
  • Generates 11 output clocks
  • Supports free-run, locked, and holdover modes of operation
  • Robust input clock source quality monitoring on all inputs
  • Automatic 'hit-less' source switchover on loss of input
  • Phase build out for output clock phase continuity during input switchover and mode transitions
  • Microprocessor interface: Intel, Motorola, serial, multiplexed, EPROM
  • Programmable wander and jitter tracking attenuation 0.1 Hz to 20 Hz
  • Support for master/slave device configuration alignment and hot/standby redundancy
  • IEEE 1149.1 JTAG boundary scan
  • Single +3.3 V operation, +5 V I/O compatible
  • Operating temperature (ambient) -40°C to +85°C
  • 100-pin LQFP package
