8V97053LNLGI/W

Overview

The 8V97053LNLGI/W is a low power wideband fractional RF synthesizer manufactured by Renesas Electronics. It features dual differential outputs with an output frequency range of 34.375MHz to 4400MHz. The device supports a 16-bit integer and 12-bit fractional (or 16-bit fractional with extended registers) architecture, utilizing a 3- or 4-wire SPI interface compatible with 1.8V logic. It operates on a single 3.3V supply, consumes 380mW typically, and includes programmable output power from -4dBm to +5dBm. Packaged in a 32-Lead 5mm x 5mm VFQFN, it is designed for multi-carrier base station radio cards.

Feature Summary

• Dual differential outputs with open-drain drivers and programmable power levels (-4dBm to +5dBm).
• Wideband frequency range from 34.375MHz to 4400MHz with integrated VCO and AutoCal feature.
• Ultra-low phase noise performance, achieving -143dBc/Hz at 1MHz offset for 1.1GHz LO.
• Supports Fractional-N and Integer-N modes via 3- or 4-wire SPI interface.

Applications

• Multi-carrier FDD and TDD base station radio cards.
• Local oscillator (LO) generation in wireless communication systems.
• Sub-GHz development and testing environments.

Procurement Notes

Verify the specific suffix 'LNLGI/W' against official Renesas documentation to confirm package type, temperature grade, and lead-free status. Ensure compatibility with the required 3.3V supply and 1.8V logic levels. Confirm availability as this component may be subject to lifecycle changes; consult current manufacturer notices for obsolescence status before finalizing procurement plans.

Selection Notes

Select this component when designing wideband RF synthesizers requiring high spectral purity and low power consumption. It is suitable for applications needing continuous frequency coverage up to 4400MHz. Consider the 32-VFQFN package constraints for PCB layout. Verify that the external loop filter design meets the stability requirements for the desired output frequencies and phase noise specifications.

Part Context

The 8V97053 series represents Renesas' wideband RF synthesizer family optimized for base station applications. This model serves as a successor or variant to earlier parts like the 8V97051, offering enhanced phase noise characteristics. It is part of the broader timing and synchronization portfolio, often supported by the Timing Commander software tool for configuration.

Replacement Considerations

The 8V97051 is listed as not recommended for new designs, with the 8V97051L suggested as a low-power alternative. Engineers transitioning from older synthesizers should verify pinout compatibility and register settings. Direct substitutes require matching the 34.375MHz to 4400MHz range and dual differential output configuration.
