Product Description

ACS8525 Line Card Protection Switch for SONET/SDH Systems QFP64 ST Original hot 

 

 

Description

The ACS8525 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 in a SONET or SDH Network Element. The
ACS8525 has fast activity monitors on the SEC clock
inputs and will implement automatic system protection
switching against the Master clock failure. The selection
of the Master/Slave input can be forced by a Force Fast
Switch pin. If both the Master and Slave input clocks fail,
the Stand-by “Group” is selected or, if no Stand-by is
available, the device enters Digital Holdover mode.
The ACS8525 can perform frequency translation,
converting, for example, an 8 kHz SEC input clock from a
backplane into a 155.52 MHz clock for local line cards.
 
 
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: two 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
‹ Selectable clock I/O port technologies
‹ Modes for E3/DS3 and multiple E1/DS1 rate output clocks
‹ Frequency translation of SEC input clock to a different local line card clock
‹ Robust input clock source activity monitoring on all 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
‹ Single 3.3 V operation, 5 V I/O compatible
‹ Operating temperature (ambient) of -40 to +85°C
‹ Available in LQFP 64 package
‹ Lead (Pb)-free version available (ACS8525T), RoHS and WEEE compliant
