8N0QV01LH-0108CDI8

Overview

The 8N0QV01LH-0108CDI8 is a quad-frequency programmable voltage-controlled crystal oscillator (VCXO) from Renesas Electronics, part of the FemtoClock NG family. 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 260MHz with a programming resolution of 435.9Hz divided by N. It features an I2C interface for configuring output frequency, absolute pull-range (APR), and internal PLL registers. The component operates on a 2.5V or 3.3V supply and includes two control inputs for selecting power-up default frequencies.

Feature Summary

• Quad-frequency programmable VCXO with I2C interface for frequency and APR configuration
• Output frequency range: 15.476MHz to 260MHz with 435.9Hz/N resolution
• Absolute pull-range (APR) programmable from ±2.5ppm to ±727.5ppm
• Low RMS phase jitter: 0.635ps typical at 156.25MHz (12kHz-20MHz)

Applications

• Wireless infrastructure equipment
• Telecommunication systems
• Networking end equipment

Part Context

This component belongs to the 8N0QV01 series of quad-frequency programmable VCXOs. It is manufactured by Renesas Electronics Corporation, formerly IDT, under the FemtoClock brand. The device is designed for applications requiring flexible frequency synthesis and precise timing control in compact packages.

Replacement Considerations

Direct replacement requires verifying pin compatibility and electrical specifications against the original design. Alternative parts within the 8N0QV01 series may offer different default frequencies or package options but must maintain I2C compatibility and similar jitter performance.
