8V97051ANLGI8

Overview

The 8V97051ANLGI8 is a low power wideband fractional RF synthesizer manufactured by Renesas Electronics Corporation. It operates as a high-performance PLL optimized for use as a local oscillator in multi-carrier, multi-mode FDD and TDD base station radio cards. The device features an integrated voltage-controlled oscillator (VCO) supporting output frequencies from 34.375MHz to 4400MHz. Key electrical parameters include a single 3.3V supply, programmable output power levels ranging from -4dBm to +5dBm (up to +7dBm with extended registers), and ultra-low phase noise of -143dBc/Hz at 1MHz offset for a 1.1GHz LO. It utilizes a 3- or 4-wire SPI interface compatible with 1.8V logic.

Feature Summary

• Dual differential outputs with open-drain configuration
• Fractional-N synthesizer architecture with 16-bit integer and 12-bit fractional resolution
• Automatic VCO band selection via AutoCal feature
• Lock detect indicators and mute function accessible via SPI or pin

Applications

• Multi-carrier base station radio cards
• Multi-mode FDD and TDD systems
• Local oscillator generation for RF transceivers

Procurement Notes

The 8V97051ANLGI8 is designated as Not Recommended for New Design (NRND). Engineers should verify current availability status through official Renesas channels. Replacement options such as the 8V97051L are available; however, functional equivalence must be confirmed against specific application requirements before procurement.

Selection Notes

Selection requires consideration of the required output frequency range up to 4400MHz and phase noise specifications. The device necessitates an external loop filter. Designers must account for the 32-Lead, 5mm x 5mm VFQFN package dimensions and ensure compatibility with the Timing Commander software tool for configuration.

Part Context

This component belongs to Renesas' RF synthesizer family, which includes variants like the 8V97053 offering enhanced phase noise specifications. The 8V97051 series is specifically engineered for telecommunications infrastructure requiring precise frequency synthesis and low jitter performance in compact form factors.

Replacement Considerations

The 8V97051L is listed as a direct alternative product within the same family. Verification of pinout compatibility and register-level functionality is required when transitioning from the NRND 8V97051ANLGI8 to the replacement part.
