Description

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.

Features

◆ 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.
