8V19N882NVGI

Overview

The 8V19N882NVGI is a FemtoClock NG jitter attenuator and clock synthesizer manufactured by Renesas Electronics. It generates high-frequency clocks and low-frequency synchronization signals (SYSREF) from a selected Voltage-Controlled Oscillator (VCO). The device supports output frequencies ranging from 0.192 MHz to 6 GHz and accepts input frequencies up to 2 GHz. It features 16 outputs in a VFQFPN-76 package, operating on supply voltages of 3.3 V, 2.5 V, or 1.8 V with a maximum operating current of 690 mA across a temperature range of -40°C to +105°C.

Feature Summary

• Generates high-frequency clocks and internally synchronized SYSREF signals for JESD204B/C applications.
• Integrated signal delay module enables phase alignment and controlled phase offset between system reference and clock signals.
• Supports four selectable clock switching modes for handling redundant input failure scenarios.
• Configurable via 3/4-wire SPI interface with internal registers and GPIO status reporting.

Applications

• JESD204B and JESD204C compliant data converter systems.
• Wireless base station radio equipment boards.
• High-performance clock conditioning for RF implementations.

Procurement Notes

Verify the specific suffix NVGI against official Renesas documentation to confirm pinout compatibility and electrical specifications. Confirm moisture sensitivity level and reflow soldering profile requirements prior to assembly. Ensure the ordering information matches the exact package dimensions and lead count listed in the datasheet.

Selection Notes

Select this component when designing systems requiring precise phase alignment and jitter attenuation for high-speed serial links. Verify that the required output frequency range falls within the 0.192 MHz to 6 GHz specification. Ensure the design accommodates the necessary supply voltage domains and SPI configuration interface constraints.

Part Context

This part belongs to the 8V19N882 series of FemtoClock NG devices. It is designed as a fully integrated solution for frequency and phase management in demanding communication infrastructure environments. The series provides optimized phase noise performance suitable for complex digital signal processing architectures.

Replacement Considerations

Consult official Renesas cross-reference documents for verified substitutes. Generic clock generators may not support the specific SYSREF synchronization or JESD204B/C compliance features inherent to this model.
