DATASHEET

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[5]

JTAG boundary scan.

Suitable for Stratum 2, 3E, 3, 4E and 4 and SONET

Minimum Clock (SMC) or SONET/SDH Equipment

Clock (SEC) applications (to Telcordia 1244-CORE[19]

Stratum 3E, and GR-253[17], and ITU-T G.812[10]

Type III and G.813[11] specifications)

Accepts 14 individual input reference clocks, all with

robust input clock source quality monitoring

Simultaneously generates nine output clocks, plus

two sync pulse outputs

Absolute Holdover accuracy better than 3 x 10-10

(manual), 7.5 x 10-14 (instantaneous); Holdover

stability defined by choice of external XO

Programmable PLL bandwidth, for wander and jitter

tracking/attenuation, 0.5 mHz to 70 Hz in 18 steps

Automatic hit-less source switchover on loss of input

Phase Transient Protection and Phase Build-out on

locked to reference and on reference switching

Microprocessor interface - Intel, Motorola, Serial,

Multiplexed, or boot from EPROM

Output phase adjustment in 6 ps steps up to ±200 ns

IEEE 1149.1 JTAG[5] Boundary Scan

Single 3.3 V operation. 5 V tolerant

Available in LQFP 100 package

Lead (Pb) - free version available (ACS8530T), RoHS

and WEEE compliant.
