9FGL0251CKILFT - Renesas Electronics

Description: The 9FGL0241/51 devices are 2-output 3.3V PCIe Gen1–5 clock generators. Each output has a dedicated OE# pin supporting PCIe CLKREQ# functionality. Two different spread spectrum levels, in addition to spread off, are supported. The 9FGL0241/51 supports PCIe Gen1–5 Common Clocked architectures (CC), PCIe Separate Reference no-Spread (SRNS) and Separate Reference Independent Spread (SRIS) clocking architectures.

9FGL0251CKILFT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the center of the board, and decoupling capacitors should be placed close to the power pins.
  • Ensure that the device is operated within the recommended temperature range (-40°C to 125°C). Use a heat sink or thermal interface material to dissipate heat, and consider using a thermal protection circuit to prevent overheating.
  • The PLL settings depend on the specific application and clock frequency requirements. Refer to the datasheet and application notes for guidance on configuring the PLL and clock settings. Typically, a PLL frequency of 100-200 MHz is recommended.
  • Use the built-in debug features, such as the JTAG interface, to debug the device. Check the device's status registers and error flags to identify the source of the issue. Consult the datasheet and application notes for troubleshooting guidelines.
  • The power supplies should be sequenced in the following order: VCC, VCCIO, and VREF. Ensure that the power supplies are stable and within the recommended voltage ranges before applying clock signals or enabling the device.
