The SY89531L programmable clock synthesizer/driver is
part of a 3.3V, high-frequency, precision PLL-based clock
synthesizer family optimized for multi-frequency, multi-
processor server, enterprise networking and other computing
applications that require the highest precision and integration.
The device integrates the following blocks into a single
monolithic IC:
PLL (Phase-Lock-Loop)-based synthesizer
Fanout buffers
Clock generator (dividers)
Logic translation (LVPECL, HSTL)
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 reference clock, see the SY89536L.
