ATCA Line Card Protection Switch for SONET/SDH AdvancedTCA Systems

Add to Watch List

The ACS8595 ATCA is a highly integrated, single-chip solution for "Hit-less" protection switching of SEC (SDH/SONET Equipment Clock) + Sync clock “Groups", from Master and Slave SETS clock cards and a third (Stand-by) source, for line cards/blades in a SONET or SDH ATCA (Advanced Telecommuncications Computing Architecture) Network Element.

Features


  • SONET/SDH applications up to OC-3/STM-1 bit rates
  • Switches between grouped inputs (SEC/Sync pairs)
  • Inputs: three SECs at any of 2, 4, 8 kHz (and N x 8 kHz multiples up to 155.52 MHz), plus Frame Sync/Multi-Frame Sync
  • Outputs: Six SEC clocks at any of several spot frequencies from 2 kHz up to 77.76 MHz via the TTL/CMOS port and up to 311.04 MHz via the PECL/LVDS port
  • Modes for E3/DS3 and multiple E1/DS1 rate output clocks
  • Generates 8 kHz Frame Sync and 2 kHz Multi-Frame Sync output clocks with programmable pulse width and polarity
  • Frequency translation of SEC input clock to different local line card clocks
  • Robust activity monitoring on all clock inputs
  • Supports Free-run, Locked and Digital Holdover modes of operation
  • Automatic "Hit-less" source switchover on loss of input
  • External force fast switch between SEC1/SEC2 inputs
  • Phase Build-out for output clock phase continuity during input switchover
  • PLL “Locked” and “Acquisition” bandwidths individually selectable from 18, 35 or 70 Hz
  • Serial interface for device set-up
  • IEEE 1149.1 JTAG Boundary Scan is supported.
  • Single 3.3 V operation, 5 V I/O compatible
  • Operating temperature (ambient) of -40 to +85°C
  • Available in 100-pin LQFP package
  • Lead (Pb)-free version (ACS8595T), RoHS and WEEE compliant
