8N4Q001EG-1015CDI8

Programmable Timers And Oscillators Overview

The Renesas 8N4Q001EG-1015CDI8 is a programmable quad-frequency voltage-controlled crystal oscillator (VCXO) belonging to the FemtoClock NG series. It utilizes fourth-generation technology to deliver low phase jitter and flexible frequency programming via an I2C interface. 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 four power-up default frequencies configurable by control pins and offers an absolute pull-range (APR) programmable from ±4.5ppm to ±754.5ppm. The component operates on a single 2.5V or 3.3V supply and is housed in a 10-lead CLCC package.
