8V97051NLGI

Overview

The 8V97051NLGI 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 +5dBm, and communicates via a 3- or 4-wire SPI interface compatible with 1.8V logic. The component is housed in a 32-lead, 5mm x 5mm VFQFN package.

Feature Summary

• Dual differential outputs with independently programmable power levels (-4dBm to +5dBm)
• Wideband frequency range: 34.375MHz to 4400MHz with integrated VCO
• Ultra-low phase noise performance (-143dBc/Hz at 1MHz offset for 1.1GHz LO)
• Supports Fractional-N and Integer-N modes with automatic VCO band selection

Applications

• Local oscillator (LO) generation for multi-carrier base station radio cards
• Multi-mode FDD and TDD wireless communication systems
• Sub-GHz development and evaluation environments

Procurement Notes

Verify the specific suffix 'L' and 'G' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging details. Confirm current product lifecycle status, as related models may be marked Not Recommended for New Design (NRND). Ensure compatibility with required external loop filter components before procurement.

Selection Notes

Select this component when a wide tuning range up to 4.4GHz is required with low power consumption (380mW typical). Verify that the 3.3V supply voltage aligns with system constraints. Consider the 32-VFQFN package dimensions for PCB layout. Ensure the application requires the specific phase noise characteristics provided for 1.1GHz operations.

Part Context

The 8V97051NLGI belongs to the 8V9705x family of wideband RF synthesizers. It is functionally similar to the 8V97051 but distinguished by its specific packaging and environmental compliance suffixes. This part is supported by the Timing Commander software tool for configuration and programming via USB.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate the 8V97051 series variants for potential functional equivalence, noting that some family members may carry Not Recommended for New Design (NRND) status.
