Product Brief WWW.SEMTECH.COM SETS and JAM PLL SONET/SDH Synchronization & Jitter Attenuation SEMTECH ADVANCED COMMUNICATIONS Key Features: • SONET/SDH system synchronization by SETS • Frequency translation and jitter attenuation by JAM PLL • Superior MTIE/TDEV figures ensure low bit-error rates • Support free-run, locked, and holdover modes • System synchronization and line card applications • ETSI/ITU/Telcordia/ANSI sync standards compliance • Applications include DSLAMs, access concentrators, add/drop multiplexers, digital cross-connects, access switches and routers, 2/3G wireless base stations and AdvancedTCA systems. • Ideal for new systems and retrofit to existing machines Semtech’s Synchronous Equipment Timing Source (SETS) family of products are employed worldwide throughout the most advanced optical telecom networks. SETS eliminates expensive discrete multi-chip configurations with a single-chip solution. Semtech’s Jitter Attenuating, Multiplying Phase Locked Loop (JAM PLL) family of products cleans up the jitter for high speed optical line cards, and provides low jitter clocks compliant up to OC-12/ STM-4 spec. JAM PLL has an integrated VCO, thus reduces the component cost and real estate on the PCB. Together with SETS parts, they offer a complete line card sync solution. Semtech revolutionizes SONET/SDH network synchronization by providing next generation solutions for higher levels of system synchronization management and overall system performance.
