8V97051NLGI/W

Overview

The 8V97051NLGI/W is a low-power wideband fractional RF synthesizer and PLL manufactured by Renesas Electronics. It operates on a single 3.3V supply and features dual differential outputs with an open-drain configuration. The device supports an output frequency range from 34.375MHz to 4400MHz, utilizing a 16-bit integer and 12-bit fractional (or 16-bit extended) architecture. It includes an integrated VCO, programmable output power levels ranging from -4dBm to +7dBm, and a mute function accessible via SPI or pin. The component is housed in a 32-lead, 5mm x 5mm VFQFN package and is designed for use as a local oscillator in multi-carrier base station radio cards.

Feature Summary

• Dual differential outputs with independently programmable power levels (-4dBm to +7dBm)
• Wideband frequency range: 34.375MHz to 4400MHz with integrated VCO
• Fractional-N synthesizer supporting Integer-N mode with 16-bit/12-bit or 16-bit extended registers
• Low phase noise performance: -143dBc/Hz at 1MHz offset for 1.1GHz LO

Applications

• Local oscillator (LO) generation for multi-carrier FDD base station radio cards
• Local oscillator (LO) generation for multi-mode TDD base station radio cards
• RF synthesizer applications requiring ultra-low phase noise and wide tuning ranges

Procurement Notes

Verify the specific suffix 'L' and 'W' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging details. Confirm current lifecycle status, as the base 8V97051 model is marked Not Recommended for New Designs (NRND). Ensure compatibility with the Timing Commander software for configuration.

Selection Notes

Select this component when a wide frequency range up to 4400MHz is required with low power consumption (380mW typical). Consider the 8V97051L variant if extended register support for higher output power (+7dBm) and fractional resolution is needed. Verify interface voltage compatibility (1.8V logic) and ensure an external loop filter is included in the design.

Part Context

The 8V97051 series belongs to Renesas' RF synthesizer family, optimized for wireless infrastructure. The 8V97051L is a low-power variant of the standard 8V97051, offering enhanced specifications such as extended register access. Evaluation kits like the EVK-8V97051 are available for development, though some may be discontinued.

Replacement Considerations

The base 8V97051 is listed as Not Recommended for New Design (NRND). Check for updated Renesas RF synthesizer models that maintain similar frequency ranges and package dimensions. Verify if the 8V97053 offers improved phase noise specifications suitable for replacement.
