8N4Q001KG-1024CDI8

Programmable Timers And Oscillators Overview

The Renesas 8N4Q001KG-1024CDI8 is a programmable clock oscillator belonging to the FemtoClock NG family. It utilizes fourth-generation technology to deliver low phase noise performance with high frequency flexibility. The device supports an I2C programming interface for configuring output frequencies, absolute pull-range (APR), and internal PLL control registers. It operates within a supply voltage range of 3.135V to 3.465V and functions reliably in ambient temperatures from -40°C to +85°C. The component is housed in a compact surface-mount package suitable for space-constrained designs.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix code against official Renesas documentation to confirm the exact factory-set default frequencies and packaging configuration. Ensure that the selected variant matches the required operating temperature range and supply voltage specifications for the target application environment before finalizing procurement.

Programmable Timers And Oscillators Selection Notes

Select this component when a programmable VCXO with low jitter is required for applications needing multiple default frequencies. Confirm that the system design can accommodate the I2C interface for dynamic reprogramming if variable frequency adjustments are necessary during operation. Verify pin compatibility with the target PCB layout.

Programmable Timers And Oscillators Part Context

This part belongs to the 8N4Q001 series of quad-frequency programmable oscillators. It shares architectural similarities with other FemtoClock NG devices but is distinguished by its specific factory-programmed default frequencies and package type. The series is designed to replace fixed-frequency crystals in complex timing architectures.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the 10-CLCC package dimensions and electrical characteristics. Verify that alternative models support the same I2C register map and APR range to ensure functional compatibility without redesigning the host controller software.
