8V97003NLGI8

Overview

The 8V97003NLGI8 is a wideband RF and microwave frequency synthesizer manufactured by Renesas Electronics. It integrates a voltage-controlled oscillator (VCO) to generate output frequencies ranging from 171.875 MHz to 18 GHz. The device features a 32-bit fractional-N feedback divider and supports both integer and fractional synthesis modes with a phase frequency detector operating up to 500 MHz in integer mode or 250 MHz in fractional mode. It operates on a single 3.3V supply with an integrated low-dropout regulator, housed in a 48-VFQFN package.

Feature Summary

• Integrated VCO providing an octave tuning range with ultra-low phase noise (-60.6 dBc at 35 fs RMS jitter).
• High figure of merit (FOM) of -236 dBc/Hz for superior spectral purity.
• Low output-to-output phase offset of 10 degrees across all operating conditions.
• Programmable RF output power levels, delivering up to +12 dBm single-ended output at 8 GHz.

Applications

• 5G radio card massive MIMO systems requiring path calibration.
• Wideband RF synthesizer applications in microwave communications.
• Ultra-low jitter clock generation for high-speed data converters.

Procurement Notes

Verify the specific suffix '8' indicates the tape-and-reel packaging variant compared to the tray version. Confirm current availability status as distribution channels may list this component as obsolete or active depending on the region. Ensure compatibility with the Timing Commander design tool for configuration.

Selection Notes

Select this model when an integrated solution covering up to 18 GHz is required without external VCOs. Compare against the non-integrated variants if discrete component flexibility is preferred. Verify input reference frequency requirements, as the device supports LVPECL, LVDS, and LVCMOS inputs within specified limits.

Part Context

This part belongs to the 8V97003 series of broadband synthesizers. The 'NLGI8' designation specifies the 48-VFQFN package with a bare pad and tape-and-reel shipping format. It serves as a core timing engine for high-frequency signal generation in advanced wireless infrastructure.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate the 8V97003NLGI (tray package) if packaging differences are acceptable. No direct cross-model functional replacements are documented.
