4 OUTPUT PCIE GEN1/2 SYNTHESIZER

IDT5V41066

Recommended Applications

Features/Benefits

4 Output synthesizer for PCIe Gen1/2

• 20-pin TSSOP package; small board footprint

• Spread-spectrum capable; reduces EMI

General Description

• Outputs can be terminated to LVDS; can drive a wider

variety of devices

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.

• 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

Output Features

• For PCIe Gen3 applications, see the 5V41236

• 4 - 0.7V current mode differential HCSL output pairs

Key Specifications

• Cycle-to-cycle jitter < 100 ps

• Output-to-output skew < 50 ps

• PCIe Gen2 phase jitter < 3.0ps RMS
