2 OUTPUT PCIE GEN1/2/3 SYNTHESIZER

5V41235

Recommended Applications

Features/Benefits

2 Output synthesizer for PCIe Gen1/2/3 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 5V41235 is a PCIe Gen2/3 compliant spread spectrum

capable clock generator. The device has 2 differential

HCSL outputs and can be used in communication or

embedded systems to substantially reduce

electro-magnetic interference (EMI). The spread amount

and output frequency are selectable via select pins. The

5V41235 can also supply 25 MHz, 125 MHz and 200 MHz

outputs for applications such as Ethernet.

• TSSOP package: 25MHz, 100MHz, 125MHz and

200MHz output frequencies.

• QFN package: 100MHz and 200MHz output frequencies.

• 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

Key Specifications

• Cycle-to-cycle jitter < 100 ps

• Output-to-output skew < 50 ps

• PCIe Gen2 phase jitter < 3.0ps RMS

• PCIe Gen3 phase jitter <1.0ps RMS
