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 clock-
tree 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 reduced
board space and power. For applications that must interface
to a crystal oscillator, see the SY89531L.
