8N0QV01EH-0009CDI

Overview

The 8N0QV01EH-0009CDI is a quad-frequency programmable voltage-controlled crystal oscillator (VCXO) manufactured by Renesas Electronics. It utilizes fourth-generation FemtoClock NG 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 single 2.5V or 3.3V supply and includes two LVCMOS/LVTTL compatible control inputs for selecting power-up default frequencies.

Feature Summary

• Quad-frequency programmable VCXO with I2C reprogrammability
• Frequency range: 15.476MHz to 260MHz; APR: ±2.5 to ±727.5ppm
• Low phase jitter: 0.635ps RMS (15.476MHz–260MHz, 12kHz–20MHz offset)
• Single 2.5V or 3.3V supply operation

Applications

• Wireless infrastructure equipment
• Telecommunication systems
• Networking end equipment

Procurement Notes

Verify the specific suffix EH-0009CDI against official Renesas documentation to confirm exact factory-set default frequencies and package details. Confirm RoHS compliance status as standard variants may differ. Check current lifecycle status, as older FemtoClock NG parts are frequently discontinued or subject to PCNs.

Selection Notes

Select this component when flexible frequency synthesis and precise pull-range adjustment are required in space-constrained designs. Ensure the system design accommodates the 10-lead ceramic package dimensions (5mm x 7mm x 1.55mm). Verify that the required output frequency falls within the 15.476MHz to 260MHz range and that the I2C bus speed matches the device capabilities.

Part Context

This part belongs to the 8N0QV01 family of quad-frequency programmable VCXOs. It shares core FemtoClock NG architecture with variants like 8N0QV01FG and 8N0QV01EG, differing primarily in the specific power-up default frequencies programmed into the factory masks and potentially minor electrical parameter variations defined by the order code.

Replacement Considerations

Direct replacements include other 8N0QV01 variants such as 8N0QV01FG-0009CDI or 8N0QV01EG-0044CDI, provided the specific default frequency requirements match. Cross-reference pinouts and register maps to ensure compatibility.
