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 PLL-
based
clock
generation
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
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.

Features
Integrated programmable synthesizer with multiple
output dividers, fanout buffers, and clock drivers
Zero-delay capability: 29.375MHz to 756MHz
Reference clock input: 9.325MHz to 756MHz
Input MUX accepts a reference and a crystal
(XTAL) source
– Ideal for reference backup clock source or
system test frequency source
– Patent-pending unique input MUX isolates XTAL
and reference inputs which minimizes crosstalk
Guaranteed AC performance:
– Output frequency range: 29.375MHz to 756MHz
– <150ps
PP
total jitter
– <6ps
RMS
cycle-to-cycle jitter (XTAL Input)
– <8ps
PP
deterministic jitter
– <0.7ps
RMS
crosstalk induced jitter
– <75ps output-to-output skew
TTL/CMOS-compatible control logic
Five-independently programmable output
frequency banks:
– Four differential LVPECL output banks
– One differential LVDS output bank with three
output pairs
Output bank synchronization control pin
Output enable
3.3V ±10% power supply (2.5V output capable)
Guaranteed over the industrial temperature range
(-40°C to +85°C)
Available in a 64-pin EPAD-TQFP
