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 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:  
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  
PLL (Phase-Lock-Loop) based synthesizer  
Zero-delay MUX and feedback capability  
1:4 LVPECL fanout  
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  
1:3 LVDS fanout  
Clock generator (dividers)  
Guaranteed AC performance:  
– Output frequency range: 29.375MHz to 756MHz  
– <150psPP total jitter  
Logic translation (LVPECL, LVDS)  
Five-independently programmable output  
banks  
– <6psRMS cycle-to-cycle jitter (XTAL Input)  
– <8psPP deterministic jitter  
This level of integration minimizes additive jitter and  
part-to-part skew associated with discrete  
– <0.7psRMS crosstalk induced jitter  
– <75ps output-to-output skew  
TTL/CMOS-compatible control logic  
Five-independently programmable output  
frequency banks:  
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.  
All support documentation can be found on  
Micrel’s web site at: www.micrel.com.  
– Four differential LVPECL output banks  
– One differential LVDS output bank with three  
output pairs  
Output bank synchronization control pin  
Output enable  
Applications  
Enterprise routers, switches, servers and  
workstations  
Parallel processor-based systems  
3.3V ±10% power supply (2.5V output capable)  
Internal system clock generation for ASICs, NPUs  
Guaranteed over the industrial temperature range  
and FPGAs  
(-40°C to +85°C)  
Available in a 64-pin EPAD-TQFP  
Markets  
LAN/WAN  
Enterprise servers
