9DB233AGLF - 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

9DB233AGLF Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APL-AN-1201) which includes thermal design considerations, such as thermal vias, copper pours, and component placement, to ensure optimal thermal performance.
  • Renesas recommends using an external overcurrent protection circuit, such as a fuse or a current sense resistor, to detect and respond to overcurrent conditions. The datasheet provides guidelines for selecting the appropriate current sense resistor value.
  • While the datasheet specifies an operating temperature range of -40°C to 125°C, Renesas recommends derating the device's performance at temperatures above 105°C to ensure reliable operation.
  • Renesas provides EMC design guidelines in their application note (APL-AN-1202) which include recommendations for PCB layout, component selection, and shielding to minimize electromagnetic interference (EMI) and ensure compliance with relevant EMC standards.
  • Renesas recommends following the JEDEC J-STD-020D.1 standard for soldering profile, which includes a peak temperature of 260°C and a dwell time of 30-60 seconds to ensure reliable solder joints.
