8V97051LNLGI

Overview

The 8V97051LNLGI is a low-power wideband fractional RF synthesizer and PLL manufactured by Renesas Electronics. It operates with a single 3.3V supply and features dual differential outputs covering a continuous frequency range from 34.375MHz to 4400MHz. The device integrates an automatic VCO band selection (AutoCal) feature and supports both fractional-N and integer-N modes via a 3- or 4-wire SPI interface compatible with 1.8V logic. Typical power consumption is 380mW with one output disabled, and it includes programmable output power levels ranging from -4dBm to +5dBm.

Feature Summary

• Dual differential open-drain outputs with independent programmable power levels (-4dBm to +5dBm).
• Wideband frequency range of 34.375MHz to 4400MHz with integrated VCO and AutoCal.
• Ultra-low phase noise performance: -143dBc/Hz at 1MHz offset for 1.1GHz LO.
• Supports 3- or 4-wire SPI interface with 1.8V logic compatibility.

Applications

• Local oscillator (LO) generation in multi-carrier base station radio cards.
• FDD and TDD wireless communication systems.
• RF synthesizer applications requiring low phase noise and wide tuning ranges.

Part Context

The 8V97051L is part of the 8V9705x family of wideband RF synthesizers. It serves as a successor or variant to the standard 8V97051, offering similar functionality within a compact 32-lead, 5mm x 5mm VFQFN package. The 'NLGI' suffix typically denotes specific packaging and tape/reel configuration details for this component.

Replacement Considerations

The 8V97051 series is marked as Not Recommended for New Designs (NRND). Designers should consider alternative timing solutions from Renesas or other manufacturers that are currently in active production and support new design implementations.
