8V97053LNLGI8

Overview

The 8V97053LNLGI8 is a low-power wideband fractional RF synthesizer manufactured by Renesas Electronics Corporation. It operates within an output frequency range of 34.375MHz to 4400MHz and utilizes a 32-lead, 5mm x 5mm VFQFN package. The device features dual differential outputs with independently programmable power levels ranging from -4dBm to +7dBm. It supports both fractional-N and integer-N modes via a 3- or 4-wire SPI interface compatible with 1.8V logic. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Wideband synthesis covering 34.375MHz to 4400MHz with integrated VCO
• Dual differential outputs with programmable power (-4dBm to +7dBm)
• Ultra-low phase noise performance at 1.1GHz LO (-143dBc/Hz at 1MHz offset)
• Supports fractional-N and integer-N modes with automatic VCO band selection

Applications

• Local oscillator (LO) in multi-carrier base station radio cards
• FDD and TDD wireless communication systems
• Sub-GHz development tools and evaluation kits

Part Context

This component belongs to the 8V9705x family of wideband RF synthesizers. It serves as a successor or variant to the 8V97051, offering enhanced specifications while maintaining compatibility with the Timing Commander software tool for configuration. The 'L' suffix typically denotes a low-power variant within this product line.

Replacement Considerations

The 8V97051 is listed as Not Recommended for New Design (NRND), with the 8V97053L identified as the direct replacement. Engineers transitioning designs should verify register compatibility using the Timing Commander software.
