8N4QV01BG-0001CD

Programmable Timers And Oscillators Overview

The Renesas 8N4QV01BG-0001CD is a quad-frequency programmable voltage-controlled crystal oscillator (VCXO) from the FemtoClock NG series. It operates on a 2.375V to 2.625V supply with a typical current consumption of 155 mA. The device supports four power-up default frequencies, including 125MHz, 100MHz, 122.88MHz, and 156.25MHz. It features an I2C interface for reprogramming output clock frequency, absolute pull-range (APR), and internal PLL control registers. The component is housed in a 10-CLCC (7x5mm) surface-mount package and functions within an ambient temperature range of -40°C to 85°C.

Programmable Timers And Oscillators Feature Summary

• Quad-frequency programmability with four power-up defaults: 125MHz, 100MHz, 122.88MHz, and 156.25MHz
• I2C programming interface for precise frequency, APR, and PLL register adjustments
• Low phase jitter performance: 0.494ps RMS at 156.25MHz (12kHz–20MHz offset)
• Operates on a single 2.375V to 2.625V supply voltage

Programmable Timers And Oscillators Applications

• Wireless infrastructure equipment requiring low phase noise clocks
• Telecommunication base stations and network synchronization systems
• Networking end equipment utilizing high-frequency timing references

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix '0001' against the official Renesas ordering guide to confirm the exact power-up frequency configuration. Confirm package availability as distribution channels may vary between trays and tubes. Check for active status or obsolescence notices prior to procurement.

Programmable Timers And Oscillators Selection Notes

Select this component when a VCXO with multiple fixed power-up frequencies is required without external configuration logic. Ensure the system design accommodates the 155mA supply current. Verify that the 10-CLCC footprint matches the PCB layout constraints and thermal requirements for the -40°C to 85°C operating range.

Programmable Timers And Oscillators Part Context

This part belongs to the Renesas FemtoClock NG family, which utilizes fourth-generation technology for optimized clock frequency and low phase noise. The 8N4QV01 series is designed for applications demanding flexible frequency programming via I2C while maintaining strict jitter specifications for high-speed data transmission.

Programmable Timers And Oscillators Replacement Considerations

Consult the IDT/Renesas FemtoClock NG replacement matrix for direct pin-compatible alternatives. Verify that any substitute maintains the 10-CLCC package dimensions and the 2.375V–2.625V supply voltage range.
