DESCRIPTION
The SY89534L and SY89535L programmable clock
synthesizers are a 3.3V, high-frequency, precision PLL-based
family optimized for multi-frequency, large clock-tree
applications that require the highest precision. These devices
integrate the following blocks into a single monolithic IC:
• PLL (Phase-Lock-Loop)-based synthesizer
• Fanout buffer
• Clock generator (divider)
• Logic translation (LVPECL, LVDS)
The SY89534L and SY89535L 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 SY89532/33.
