8V97053NLGI

Overview

The 8V97053NLGI 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 with extended registers) architecture via 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 (+7dBm with extended registers). Packaged in a 32-Lead 5mm x 5mm VFQFN, it offers ultra-low phase noise and automatic VCO band selection.

Feature Summary

• Dual differential outputs with continuous frequency range from 34.375MHz to 4400MHz
• Ultra-low phase noise performance: -143dBc/Hz at 1MHz offset for 1.1GHz LO
• Programmable output power levels ranging from -4dBm to +5dBm (+7dBm with extended registers)
• Integrated VCO with automatic band selection (AutoCal) and mute function

Applications

• Local oscillator (LO) in multi-carrier base station radio cards
• Multi-mode FDD and TDD base station systems
• Sub-GHz development and testing environments

Procurement Notes

Verify the specific suffix 'NLGI' against official Renesas documentation to confirm package type, tape-and-reel specifications, and lead-free status. Confirm current production status as some variants in this family may be marked Not Recommended for New Design (NRND). Ensure compatibility with the Timing Commander software tool for configuration.

Selection Notes

Select the 8V97053NLGI when ultra-low phase noise is critical for 1.1GHz applications compared to other family members. Verify that the required output frequency range fits within the 34.375MHz to 4400MHz limit. Check if the integrated VCO meets spurious requirements without external filtering beyond the standard loop filter. Confirm SPI voltage compatibility with the system's 1.8V logic levels.

Part Context

The 8V97053 is part of Renesas' wideband RF synthesizer family, positioned alongside the 8V97051. While the 8V97051 is noted as Not Recommended for New Design, the 8V97053 offers enhanced phase noise specifications specifically optimized for 1.1GHz local oscillator applications in cellular infrastructure.

Replacement Considerations

The 8V97051L is listed as a low-power alternative to the 8V97051, but direct substitution requires verifying phase noise and frequency coverage differences. No other direct public substitutes are confirmed for the 8V97053NLGI specifically.
