PI6C49X0204B-A
Low Skew, 1-TO-4 LVCMOS/LVTTL
Fanout Buffer
Description
Features
ÎÎFour LVCMOS / LVTTL outputs
ÎÎLVCMOS / LVTTL clock input
The PI6C49X0204B-A is a low skew, 1-to-4 Fanout Buffer.
Guaranteed output and part-to-part skew characteristics make the
PI6C49X0204B-A ideal for those clock distribution applications
demanding well defined performance and repeatability.
ÎÎCLK can accept the following input levels: LVCMOS, LVTTL
ÎÎMaximum output frequency: 200MHz
ÎÎAdditive phase jitter, RMS: 0.06ps (typical) @ 3.3V
ÎÎOutput skew: 45ps (maximum) @ 3.3V
ÎÎPart-to-part skew: 500ps (maximum)
ÎÎSmall 8 lead SOIC package saves board space
ÎÎ3.3V core supply, 3.3V or 2.5V output supply
ÎÎ0°C to 70°C ambient operating temperature

Parameters measured at f MAX unless otherwise noted.
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.
NOTE 4: Defined from 20% to 80%

Phase Noise and Additive Jitter
Output phase noise (Right plot) vs Input Phase noise (Left plot)
Additive jitter is calculated at ~60.2fs RMS (12kHz to 20MHz). Additive jitter = √(Output jitter2 - Input jitter2)
