IDT5V41064
REV G 112111
Recommended Applications
One output synthesizer for PCIe Gen1/2
General Description
The IDT5V41064 is a PCIe Gen2 compliant spread
spectrum capable clock generator. The device has 1
differential HCSL output and can be used in communication
or embedded systems to subtantially reduce
electro-magnetic interference (EMI). Spread spectrum can
be enabled via a select pin.
Output Features
1 - 0.7V current mode differential HCSL output pairs
Features/Benefits
16-pin QFN package; very small board footprint
Spread-spectrum capable; reduces EMI
Outputs can be terminated to LVDS; can drive a wider
variety of devices
Spread enable via pin selection; no software required to
configure device
Industrial temperature range available; supports
demanding embedded applications
For PCIe Gen3 applications, see the 5V41234
