PI6C49X0202
Low Skew, 1-To-2 LVCMOS / LVTTL Fanout Buffer
Description
The PI6C49X0202 is a low skew, 1-to-2 LVCMOS/LVTTL
High Performance Fanout Buffer. The PI6C49X0202 has a
Features
ꢀÎ2 LVCMOS / LVTTL outputs
ꢀÎLVCMOS / LVTTL clock input accepts LVCMOS or LVTTL
single ended clock input. The single ended clock input accepts
LVCMOS or LVTTL input levels. The PI6C49X0202 features a
pair of LVCMOS/LVTTL outputs. Guaranteed output and part-to-
part skew characteristics make the PI6C49X0202 ideal for clock
distribution applications demanding well defined performance
and repeatibility.
input levels
ꢀÎMaximum output frequency: 250MHz
ꢀÎOutput skew: 25ps (typical)
ꢀÎPart-to-part skew: 250ps (typical)
ꢀÎSmall 8 lead SOIC package saves board space
ꢀÎFull 3.3V, 2.5V operation modes
ꢀÎ-40°C to 85°C ambient operating temperature
ꢀÎLead-Free package fully RoHS compliant
