8V97051ANLGI/W

Overview

The 8V97051ANLGI/W is a low-power wideband fractional RF synthesizer and PLL optimized for use as a local oscillator in multi-carrier, multi-mode FDD and TDD base station radio cards. It features an integrated voltage-controlled oscillator (VCO) supporting output frequencies from 34.375MHz to 4400MHz with superior phase noise performance. The device offers dual differential outputs with independently programmable power levels ranging from -4dBm to +7dBm. It utilizes a 3- or 4-wire SPI interface compatible with 1.8V logic and operates on a single 3.3V supply. Key specifications include ultra-low phase noise of -143dBc/Hz at 1MHz offset for a 1.1GHz LO and typical power consumption of 380mW.

Feature Summary

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

Applications

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

Part Context

The 8V97051 series belongs to Renesas' RF synthesizer family, designed for high-performance timing applications. The 'A' suffix typically denotes specific manufacturing lot or revision details within the NLGI package variant. This component is part of a broader portfolio that includes variants like the 8V97052 and evaluation kits such as the EVK-8V97051 for development purposes.

Replacement Considerations

The standard 8V97051 is marked as Not Recommended for New Designs (NRND). Engineers should consider the 8V97051L as the designated low-power replacement within the same family. Verify pin compatibility and register settings when migrating from the original 8V97051 to the L-series variant.
