IDT5V41065 APRIL 17, 2017
Recommended Applications
2 Output synthesizer for PCIe Gen1/2 and Ethernet
General Description
The IDT5V41065 is a PCIe Gen2 compliant spread
spectrum capable clock generator. The device has 2
differential HCSL outputs and can be used in
communication or embedded systems to substantially
reduce electro-magnetic interference (EMI). The spread
amount and output frequency are selectable via select pins.
The IDT5V41065 can also supply 25 MHz, 125 MHz and
200 MHz outputs for applications such as Ethernet.
Output Features
• 2 - 0.7V current mode differential HCSL output pairs
Features/Benefits
• 16-pin TSSOP and QFN packages; small board footprint
• Spread-spectrum capable; reduces EMI
• Outputs can be terminated to LVDS; can drive a wider
variety of devices
• 25 MHz, 125 MHz and 200 MHz output frequencies;
TSSOP only
• 100MHz and 200MHz output frequencies; VFQFPN
package
• OE control pin; greater system power management
• Spread% and frequency pin selection; no software
required to configure device
• Industrial temperature range available; supports
demanding embedded applications
• For PCIe Gen3 applications, see the 5V41235
Key Specifications
• Cycle-to-cycle jitter < 100 ps
• Output-to-output skew < 50 ps
• PCIe Gen2 phase jitter < 3.0ps RMS
