8N4QV01LG-0147CDI8

Programmable Timers And Oscillators Overview

The Renesas 8N4QV01LG-0147CDI8 is a Quad-Frequency Programmable Voltage-Controlled Crystal Oscillator (VCXO) utilizing FemtoClock NG technology. It operates on a single 2.5V or 3.3V supply and features an I2C interface for precise frequency programming, APR adjustment, and PLL control. The device provides one LVDS differential clock output with low phase jitter characteristics. It supports four power-up default frequencies selectable via hardware pins and allows reprogramming through the I2C bus. The component is housed in a compact 10-lead CLCC package suitable for space-constrained designs.
