Recommended Applications
4 Output synthesizer for PCIe Gen1/2
General Description
The IDT5V41066 is a PCIe Gen2 compliant spread-spectrum-capable clock generator. The device has 4 differential HCSL outputs and can be used in communication or embedded systems to subtantially reduce electro-magnetic interference (EMI). The spread amount and output frequency are selectable via select pins.
Output Features
4 - 0.7V current mode differential HCSL output pairs
Features/Benefits
20-pin TSSOP package; small board footprint Spread-spectrum capable; reduces EMI Outputs can be terminated to LVDS; can drive a wider
variety of devices
Power down pin; greater system power management 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 5V41236
