8V97053LNLGI

Overview

The 8V97053LNLGI is a low-power wideband fractional RF synthesizer/PLL manufactured by Renesas Electronics. It features an integrated voltage-controlled oscillator (VCO) and dual differential outputs, supporting a continuous frequency range from 34.375MHz to 4400MHz. The device utilizes a 16-bit integer and 12-bit fractional architecture, with extended registers enabling 16-bit fractional mode. It operates on a single 3.3V supply and includes programmable output power levels ranging from -4dBm to +7dBm. The component is housed in a compact 32-lead, 5mm x 5mm VFQFN package and supports automatic VCO band selection via the AutoCal feature.

Feature Summary

• Dual differential outputs with independent programmable power levels (-4dBm to +7dBm)
• Integrated VCO supporting 34.375MHz to 4400MHz continuous frequency range
• Fractional-N synthesizer with 16-bit integer and 12-bit fractional resolution
• Ultra-low phase noise performance: -143dBc/Hz at 1MHz offset for 1.1GHz LO

Applications

• Local oscillator (LO) generation for multi-carrier base station radio cards
• FDD and TDD wireless communication systems
• High-performance RF signal generation requiring low phase noise

Procurement Notes

Verify the specific suffix 'LNLGI' against official Renesas documentation to confirm package type, temperature grade, and lead-free status. Ensure compatibility with the Timing Commander software for configuration. Check current product lifecycle status as previous models in this family have been marked Not Recommended for New Designs.

Selection Notes

Select this component when a wide tuning range up to 4.4GHz is required with integrated VCO capabilities. Consider the 3.3V supply requirement and SPI interface compatibility. Evaluate the need for dual differential outputs versus single-ended alternatives. Verify thermal management requirements for the VFQFN package in the target application environment.

Part Context

The 8V97053 series represents Renesas' high-performance RF synthesizers optimized for telecommunications infrastructure. It succeeds earlier generations like the 8V97051, offering enhanced phase noise specifications and integrated VCO functionality. This family is designed to replace discrete PLL solutions, reducing board space and design complexity for base station applications.

Replacement Considerations

The 8V97051 is listed as a related product but marked Not Recommended for New Design. Direct pin-to-pin replacement requires verification of electrical parameter differences, particularly phase noise and output power characteristics. Consult Renesas for current active equivalents if the 8V97053LNLGI is discontinued.
