IDT5V41064 Datasheet, PDF (1/12 Pages) Integrated Device Technology – 1 OUTPUT PCIE GEN1/2 SYNTHESIZER Spread-spectrum capable; reduces EMI

1 OUTPUT PCIE GEN1/2 SYNTHESIZER
DATASHEET
IDT5V41064
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
Key Specifications
• Cycle-to-cycle jitter < 100 ps
• PCIe Gen2 phase jitter < 3.0ps RMS
