8V19N850NLGI

Overview

The 8V19N850NLGI is a clock synchronizer from the Renesas 8V19N850 series, designed for wireless radio applications. It functions as a clock generator and support product, providing precise timing signals required for RF front-end modules and baseband processors in cellular infrastructure. The device integrates multiple voltage-controlled oscillators (VCOs) and phase-locked loops (PLLs) to generate low-jitter clock outputs with flexible frequency synthesis capabilities.

Feature Summary

• Integrated dual VCO architecture for wide frequency range coverage
• Low jitter performance optimized for wireless communication standards
• Flexible output configuration supporting multiple clock domains
• I2C/SPI programmable interface for dynamic frequency adjustment

Applications

• 4G LTE and 5G NR base station RF units
• Wireless backhaul equipment
• Small cell and distributed antenna systems

Procurement Notes

Verify the specific suffix 'DNLGI' against official Renesas documentation to confirm package type, temperature grade, and lead-free status. Confirm minimum order quantities and reel specifications directly with authorized distributors or the manufacturer, as these parameters are subject to change based on production lot and regional availability.

Selection Notes

Select this component when designing wireless radio systems requiring synchronized multi-clock outputs with stringent jitter specifications. Ensure the input reference frequency matches the device's supported range and that the power supply voltages align with the system's available rails. Verify thermal requirements for the intended operating environment.

Part Context
