8V97053NLGI8

Overview

The 8V97053NLGI8 is a wideband RF synthesizer and PLL from Renesas Electronics, part of the VersaClock family. It features an integrated voltage-controlled oscillator (VCO) and supports output frequencies from 34.375MHz to 4400MHz. The device utilizes a fractional-N architecture with 16-bit integer and 12-bit fractional resolution, expandable to 16-bit fractional via extended registers. It offers dual differential outputs with programmable power levels ranging from -4dBm to +7dBm. Configuration is managed through a 3- or 4-wire SPI interface compatible with 1.8V and 3.3V logic. The component operates on a single 3.3V supply with typical power consumption of 380mW.

Feature Summary

• Integrated VCO supporting continuous frequency range of 34.375MHz to 4400MHz
• Dual differential outputs with programmable power (-4dBm to +7dBm) and mute function
• Fractional-N synthesizer with 16-bit integer and 12/16-bit fractional resolution
• Ultra-low phase noise performance, e.g., -143dBc/Hz at 1MHz offset for 1.1GHz LO

Applications

• Local oscillator (LO) in multi-carrier base station radio cards
• FDD and TDD cellular infrastructure systems
• Wideband RF signal generation requiring low phase noise

Procurement Notes

Verify the specific suffix 'NLGI8' against official Renesas documentation to confirm package type, tape-and-reel specifications, and RoHS compliance status. Ensure compatibility with the Timing Commander software tool for configuration. Check current product lifecycle status as RF synthesizers may transition to NRND status.

Selection Notes

Select this component when a wideband frequency range up to 4.4GHz is required with integrated VCO capabilities. Compare phase noise specifications against system requirements, particularly at 1MHz offsets. Verify that the 3.3V supply and SPI interface align with the host system's voltage domains and control bus availability.

Part Context

The 8V97053 is part of Renesas' VersaClock 5 series, designed for high-performance timing applications. It serves as an enhanced variant within the 8V9705x family, offering improved phase noise characteristics compared to predecessors like the 8V97051. The device is supported by evaluation kits such as the 8V97053-EVK for development purposes.

Replacement Considerations

The 8V97051 is listed as a related product but is marked Not Recommended for New Designs (NRND). The 8V97051L is suggested as a low-power alternative. Verify pinout and register compatibility before substituting.
