DESCRIPTION
Precision Edge®
The SY89536L programmable clock synthesizer is part of a 3.3V, high-frequency, precision PLL-based clock synthesizer family optimized for multi-frequency, large clocktree applications. This device integrates the following blocks into a single monolithic IC:
PLL (Phase-Lock-Loop)-based synthesizer Fanout buffer Clock generator (divider) Logic translation (LVPECL, HSTL)
The SY89536L includes a flexible input design that accepts any reference input; single-ended LVTTL/
CMOS, SSTL and differential LVPECL, LVDS, HSTL, and CML.
This level of integration minimizes the additive jitter and part-to-part skew associated with the discrete alternative, resulting in superior system-level timing as well as...
