9FGV1004BQ53ALTGI8

Overview

The Renesas 9FGV1004BQ53ALTGI8 is a programmable PhiClock generator designed for high-performance timing applications. It supports PCIe Gen1 through Gen4 compliance, delivering typical phase jitter of 267fs RMS at 156.25MHz (12kHz–20MHz). The device features four programmable differential output pairs and two LVCMOS reference outputs, supporting LP-HCSL and LVDS signaling standards. Operating with a 1.8V core voltage and individual 1.8V to 3.3V VDDO supplies, it accommodates frequencies from 1MHz to 325MHz. Packaged in a compact 4x4mm 24-VFQFPN or 24-LGA format, it integrates hardware selection via select pins or I2C software configuration.
