The SY58021U is a 2.5V/3.3V precision, high-speed, fully  
differential 1:4 LVPECL fanout buffer. Optimized to provide  
four identical output copies with less than 15ps of skew and  
• <300ps t

• <15ps max skew  
less than 10ps total jitter, the SY58021U can process  
pp  
clock signals as fast as 4GHz.  
• <10ps total jitter (clock)  
pp  
The differential input includes Micrel’s unique, 3-pin input  
termination architecture interfaces to differential LVPECL,  
CML, and LVDS signals (AC- or DC-coupled) as small as  
100mV without any level-shifting or termination resistor  
networks in the signal path. For AC-coupled input interface

applications, an on-board output reference voltage (V

) is provided to bias the VT pin. The outputs are 100k  
AC  
LVPECL compatible, with extremely fast rise/fall times  
guaranteed to be less than 100ps.  
The SY58021U operates from a 2.5V ±5% supply or  
3.3V ±10% supply and is guaranteed over the full industrial  
temperature range (–40°C to +85°C). For applications that  
require faster rise/fall times, or greater bandwidth, consider  
the SY58022U 1:4 fanout buffer with 400mV LVPECL output  
swing, or the SY58020U 1:4 CML fanout buffer. The
