2 OUTPUT PCIE GEN1/2 SYNTHESIZER
DATASHEET
IDT5V41285
Recommended Applications
2 output synthesizer for PCIe Gen1/2 and Ethernet
General Description
The IDT5V41285 is a PCIe Gen2 compliant clock
generator. The device has 2 differential HCSL outputs. The
output frequency is selectable via select pins.
Output Features
• 2 - Non-spread 0.7V current mode differential HCSL
output pairs
Features/Benefits
• 16-pin TSSOP and VFQFPN packages; small board
footprint
• Outputs can be terminated to LVDS; can drive a wider
variety of devices
