Overview

Description

The 9FGV0241 is a 2-output very low power frequency generator for PCIe Gen 1–4 applications with integrated output terminations providing Zo = 100Ω. The device has two output enables for clock management and supports two different spread spectrum levels in addition to spread off.

Features

  • PCIe Gen 1–4 compliant
  • Integrated terminations provide 100Ω differential Zo: reduced component count and board space
  • 1.8V operation: reduced power consumption
  • OE# pins: support DIF power management
  • LP-HCSL differential clock outputs: reduced power and board space
  • Programmable slew rate for each output: allows tuning for various line lengths
  • Programmable output amplitude: allows tuning for various application environments
  • DIF outputs are blocked until PLL is locked: clean system start-up
  • Selectable 0%, -0.25%, or -0.5% spread on DIF outputs: reduces EMI
  • External 25MHz crystal; supports tight ppm with 0ppm synthesis error
  • Configuration can be accomplished with strapping pins: SMBus interface is not required for device control
  • 3.3V tolerant SMBus interface works with legacy controllers
  • Space-saving 4mm x 4mm 24-pin VFQFPN; minimal board space

  1. RZV2M ISP integration issue

    We have created a board based on the RZ/V2M processor. The only change we made compared to the RZV2M EVK is that we swapped the DDR data pins. We also made the necessary changes to the bootloader sources to accommodate these modifications. I am able to boot Linux ...
