8N4Q001FG-0005CDI8

Programmable Timers And Oscillators Overview

The 8N4Q001FG-0005CDI8 is a programmable quad-frequency voltage-controlled crystal oscillator (VCXO) from Renesas Electronics Corporation, part of the FemtoClock NG series. It utilizes fourth-generation technology to deliver high clock frequencies with low phase noise. The device supports output frequencies ranging from 15.476MHz to 866.67MHz and 975MHz to 1,300MHz, with a programming resolution of 435.9Hz ÷N. It features an I2C interface for frequency, APR, and PLL control, along with two LVCMOS/LVTTL-compatible control inputs for selecting power-up default frequencies. The component operates on a 2.5V or 3.3V supply within a -40°C to 85°C temperature range.
