4 OUTPUT PCIE GEN1/2 SYNTHESIZER 1
IDT5V41066 REV D 112211
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
