8N4QV01KG-1076CDI8

Programmable Timers And Oscillators Overview

The Renesas 8N4QV01KG-1076CDI8 is a quad-frequency programmable voltage-controlled crystal oscillator (VCXO) from the FemtoClock NG series. It utilizes fourth-generation technology to deliver high clock frequency and low phase noise performance. The device supports output frequencies ranging from 15.476MHz to 866.67MHz and 975MHz to 1,300MHz with a resolution of 435.9Hz ÷N. It features an I2C interface for programming output frequency, absolute pull-range (APR), and internal PLL registers. The component operates on a single 2.5V or 3.3V supply and provides one LVDS differential clock output.

Programmable Timers And Oscillators Feature Summary
