SY89538L
3.3V, Precision LVPECL and LVDS
Programmable Multiple Output Bank Clock
Synthesizer and Fanout Buffer with Zero Delay General Description
The SY89538L integrated programmable clock
synthesizer and fanout is part of a precision PLLbased clock generation family optimized for
enterprise switch, router, and multiprocessor server
applications. This family is ideal for generating
internal system timing requirements up to 750MHz for
multiple ASICs, FPGAs, and NPUs. These devices
integrate the following blocks into a single monolithic
IC: PLL (Phase-Lock-Loop) based synthesizer Zero-delay MUX and feedback capability 1:4 LVPECL fanout 1:3 LVDS fanout Clock generator (dividers) Logic translation (LVPECL, LVDS) Five-independently programmable output
banks
This level of integration minimizes additive jitter and
part-to-part
skew
associated
with
discrete
alternatives, resulting in superior system-level timing
with reduced board space and power. For
applications that do not require a zero-delay function,
see the SY89537L. …
