8V97051LNLGI/W

Overview

The 8V97051LNLGI/W is a low power wideband fractional RF synthesizer and PLL optimized for use as the local oscillator in multi-carrier, multi-mode FDD and TDD base station radio cards. It features dual differential outputs with an output frequency range of 34.375MHz to 4400MHz. The device supports a 3- or 4-wire SPI interface compatible with 1.8V logic and operates on a single 3.3V supply. Key electrical parameters include programmable output power from -4dBm to +5dBm (up to +7dBm with extended registers), typical phase noise of -143dBc/Hz at 1MHz offset for 1.1GHz LO, and typical power consumption of 380mW. It is housed in a 32-lead, 5mm x 5mm VFQFN package.

Feature Summary

• Dual differential outputs with open-drain configuration
• Fractional-N synthesizer supporting Integer-N mode
• Programmable output power: -4dBm to +5dBm (+7dBm extended)
• Ultra-low phase noise: -143dBc/Hz at 1MHz offset (1.1GHz LO)

Applications

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

Procurement Notes

Verify component status before procurement as the 8V97051 family is designated Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting that stock may be limited or discontinued. Ensure compatibility with existing design constraints given the end-of-life status.

Selection Notes

Select this component only for legacy system maintenance or upgrades where the 8V97051 family is already integrated. For new designs, consider alternative Renesas RF synthesizers such as the 8V97053 which offers enhanced phase noise specifications. Verify that the required frequency range and power levels align with the device's capabilities.

Part Context

The 8V97051LNLGI/W belongs to the 8V97051 series of wideband RF synthesizers manufactured by Renesas Electronics. This series is designed for high-performance wireless infrastructure applications. The 'L' suffix typically denotes a specific variant within the family, often related to power consumption or pinout compatibility with other models like the 8V97051.

Replacement Considerations

The 8V97051 series is Not Recommended for New Design. Potential replacements include the 8V97053, which provides enhanced phase noise performance. Evaluate pin-to-pin compatibility and software register settings when migrating to alternative components.
