The ACS8530 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 ACS8530 is fully
compliant with the required international 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 ACS8530 generates independent
SEC and BITS clocks, an 8 kHz Frame Synchronization
clock and a 2 kHz Multi-Frame Synchronization clock.
Two ACS8530 devices can be used together in a Master/
Slave configuration mode allowing system protection
against a single ACS8530 failure.
A microprocessor port is incorporated, providing access to
the configuration and status registers for device setup
and monitoring. The ACS8530 supports IEEE 1149.1
JTAG boundary scan.
