General Description
The SY89538L integrated programmable clock
synthesizer and fanout is part of a precision PLL-
based
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.

Micrel’s web site at: www.micrel.com.
Applications
Enterprise routers, switches, servers and
workstations
Parallel processor-based systems
Internal system clock generation for ASICs, NPUs
and FPGAs
Markets
LAN/WAN
Enterprise servers
Test and measurement
Precision Edge
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
– <150psPP total jitter
– <6psRMS cycle-to-cycle jitter (XTAL Input)
– <8psPP deterministic jitter
– <0.7psRMS 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
