8N4QV01EG-0047CDI

Programmable Timers And Oscillators Overview

The Renesas 8N4QV01EG-0047CDI is a Quad-Frequency Programmable VCXO utilizing fourth-generation FemtoClock NG technology. It operates on a single 2.5V or 3.3V supply and features one LVDS differential clock output. The device supports programmable frequencies from 15.476MHz to 866.67MHz and 975MHz to 1,300MHz with a resolution of 435.9Hz ÷N. Absolute pull-range (APR) is configurable from ±4.5ppm to ±754.5ppm via I2C. Typical RMS phase jitter at 156.25MHz is 0.494ps (12kHz–20MHz). It is housed in a 10-lead ceramic package.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'EG' against official Renesas documentation to confirm exact default frequencies and electrical characteristics. Confirm RoHS compliance status as indicated in manufacturer datasheets. Check for current lifecycle status, as similar variants in this series are marked as obsolete or limited supply.

Programmable Timers And Oscillators Selection Notes

Select this component when low phase jitter and wide frequency agility are required. Ensure the design supports I2C programming for dynamic frequency and APR adjustments. Verify that the system can accommodate the 10-CLCC package dimensions and thermal requirements within the -40°C to 85°C operating range.

Programmable Timers And Oscillators Part Context

This part belongs to the 8N4QV01 family of quad-frequency programmable VCXOs. It shares core architecture with other suffixes like 8N4QV01FG and 8N4QV01KG, differing primarily in factory-programmed default frequencies and potentially packaging variations. All variants utilize the same 10-lead ceramic footprint.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes include other 8N4QV01 variants such as 8N4QV01FG-0074CDI or 8N4QV01KG-0121CDI8, provided the default frequency settings match application requirements. Pin compatibility is maintained across the family.
