9DBL0453ANLGI

Overview

The 9DBL0453ANLGI is a 4-output, 3.3V PCIe zero-delay/fanout clock buffer from Renesas Electronics. It supports PCIe Gen 1 through Gen 6 architectures, including Common Clock (CC) and Independent Reference (IR) modes with spread spectrum tolerance. The device features four Low Power HCSL (LP-HCSL) outputs that eliminate the need for external termination resistors per output pair. It offers additive phase jitter performance of less than 18fs RMS in fanout mode and less than 100fs RMS in high-bandwidth zero-delay buffer mode. Operating frequencies range from 1MHz to 200MHz. The component is housed in a space-saving 32-pin, 5mm x 5mm VFQFPN package.
