PI6LC4830
HiFlexTM Network Clock Generator
Features
ÎÎ3.3V supply voltage
ÎÎ3 HCSL and 1 LVCMOS 100MHz outputs with OE/ function
ÎÎ1 LVCMOS 100/50MHz selectable
ÎÎ25MHz crystal or differential input
ÎÎLow 1ps RMS max integrated phase noise design
ÎÎPLL Bypass mode for test
ÎÎ32 lead 5x5mm TQFN package
Description
The PI6LC4830 is an LC VCO based low phase noise design
intended for the most demanding PCIe® 2.0 applications. Use
of the ultra-low noise LC VCO allows for much greater noise
margins than traditional solutions. This is ideal for noisy envi-
ronments.
