9DB233AGLFT - Renesas Electronics

Description: The 9DB233 zero-delay buffer supports PCIe Gen3 requirements, while being backwards compatible to PCIe Gen2 and Gen1. The 9DB233 is driven by a differential SRC output pair from an IDT 932S421 or 932SQ420 or equivalent main clock generator. It attenuates jitter on the input clock and has a selectable PLL bandwidth to maximize performance in systems with or without Spread-Spectrum clocking. An SMBus interface allows control of the PLL bandwidth and bypass options, while 2 clock request (OE#) pins make the 9D

9DB233AGLFT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a low-impedance path for the power traces and keep the switching node (SW) away from sensitive analog nodes.
  • Use the provided compensation network calculation tool or consult the application note for guidance. Ensure the compensation network is optimized for the specific output capacitor and load conditions.
  • The maximum allowed input voltage ripple is 10% of the input voltage. Exceeding this may affect the device's reliability and performance.
  • Follow the recommended PCB layout and component placement guidelines. Ensure proper shielding, filtering, and decoupling to minimize electromagnetic interference (EMI).
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 4.7 μF to 10 μF is recommended. This ensures stable operation and minimizes input voltage ripple.
