PI6C49X0202
Low Skew, 1-To-2 LVCMOS / LVTTL Fanout Buffer
Description
Features
The PI6C49X0202 is a low skew, 1-to-2 LVCMOS/LVTTL
High Performance Fanout Buffer. The PI6C49X0202 has a
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-topart skew characteristics make the PI6C49X0202 ideal for clock
distribution applications demanding well defined performance
and repeatibility.
ÎÎ2 LVCMOS / LVTTL outputs
ÎÎLVCMOS / LVTTL clock input accepts LVCMOS or LVTTL
input levels
ÎÎMaximum output frequency: 250MHz
ÎÎOutput skew: 25ps (typical)
ÎÎPart-to-part skew: 250ps (typical)
ÎÎSmall 8 lead SOIC package saves board space
ÎÎFull 3.3V, 2.5V operation modes
ÎÎ-40°C to 85°C ambient operating temperature
ÎÎLead-Free package fully RoHS compliant

NOTE 1: Measured from VDD /2 of the input to VDDO /2 of the output.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDDO /2.
NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltages and with equal load
conditions. Using the same type of inputs on each device, the outputs are measured at VDDO /2.
