SY89537LMGTR [MICREL]

The SY89537L is a programmable clock synthesizer and fanout buffer that integrates a PLL-based synthesizer, fanout buffers, clock dividers, and logic translation (LVPECL/LVDS) into a single monolithic IC. It generates internal system timing up to 700MHz for ASICs, FPGAs, and NPUs, minimizing additive jitter and part-to-part skew while reducing board space and power. Features include five independently programmable output banks (four LVPECL and one LVDS with 3 pairs), input MUX for crystal or reference clock, guaranteed AC performance with low jitter (<100ps total jitter, <7ps cycle-to-cycle jitter RMS), output bank synchronization, TTL/CMOS-compatible control logic, separate output enables per bank, 3.3V ±10% supply (2.5V output capable), and industrial temperature range (-40°C to +85°C). Available in a 44-pin MLF package.
