2 OUTPUT PCIE GEN1/2 SYNTHESIZER
IDT5V41065
Recommended Applications
Features/Benefits
2 Output synthesizer for PCIe Gen1/2 and Ethernet
• 16-pin TSSOP and QFN packages; small board footprint
• Spread-spectrum capable; reduces EMI
General Description
• Outputs can be terminated to LVDS; can drive a wider
variety of devices
The IDT5V41065 is a PCIe Gen2 compliant spread
spectrum capable clock generator. The device has 2
differential HCSL outputs and can be used in
• 25 MHz, 125 MHz and 200 MHz output frequencies;
TSSOP only
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.
• 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
Output Features
• 2 - 0.7V current mode differential HCSL output pairs
• 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
