8V19N492NLGI

Overview

The 8V19N492NLGI is a high-performance clock RF-PLL jitter attenuator optimized for low phase noise applications. It supports JESD204B/C standards and generates high-frequency clocks from a selected VCO along with low-frequency synchronization signals (SYSREF). The device features an increased number of low-noise outputs designed for direct DAC/ADC sample clock generation, enabling precise timing in complex data conversion systems.

Feature Summary

• Supports JESD204B/C standards for high-speed data converter synchronization
• Optimized for ultra-low phase noise performance
• Generates direct DAC/ADC sample clocks via multiple low-noise outputs
• Provides dedicated SYSREF signal generation capabilities

Applications

• Wireless infrastructure base stations
• Radar and imaging systems
• High-end instrumentation and medical devices

Procurement Notes

Verify the specific suffix 'NLGI' against official Renesas documentation to confirm package type and temperature range. Ensure compatibility with JESD204B/C system requirements before procurement. Confirm that the device core voltage and I2C interface settings align with the target board design specifications.

Selection Notes

Select this component when ultra-low phase noise is critical for ADC/DAC performance. It is suitable for designs requiring direct sample clock generation without external buffering. Consider the output count and frequency range requirements to ensure it meets the system's timing architecture needs compared to standard synthesizers.

Part Context

This part belongs to Renesas' clock generator family, previously associated with IDT technology. It is designed for high-speed serial data transmission interfaces. The device integrates RF-PLL technology to provide stable clocking solutions for demanding digital signal processing applications in communication and measurement sectors.

Replacement Considerations

Check for updated suffixes or revised revisions in the official datasheet. Verify pinout and electrical parameter equivalence if substituting with other JESD204B-compatible jitter attenuators from the same product line.
