8V97053NLGI/W

Overview

The 8V97053NLGI/W is a wideband RF synthesizer and PLL with an integrated voltage-controlled oscillator (VCO), manufactured by Renesas Electronics. It serves as a local oscillator in multi-carrier, multi-mode FDD and TDD base station radio cards. The device supports output frequencies from 34.375MHz to 4400MHz, maintaining superior phase noise and spurious performance. It features dual differential outputs with independently programmable power levels ranging from -4dBm to +7dBm. The component utilizes a 16-bit integer and 12-bit fractional synthesis architecture via a 3- or 4-wire SPI interface compatible with 1.8V logic. It operates on a single 3.3V supply within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Wideband frequency range: 34.375MHz to 4400MHz with integrated VCO
• Dual differential outputs with programmable power (-4dBm to +7dBm)
• Fractional-N and Integer-N synthesis modes with low phase noise
• 3- or 4-wire SPI interface compatible with 1.8V logic

Applications

• Multi-carrier base station radio cards
• Multi-mode FDD and TDD systems
• Local oscillator generation for wireless infrastructure

Part Context

The 8V97053 is part of the Renesas 8V97xxx series of wideband RF synthesizers. It shares architectural similarities with the 8V97051 but offers enhanced phase noise specifications. The 'NLGI' suffix indicates the specific package type (VFQFN) and lead-free packaging, while '/W' denotes the industrial temperature grade. This component is designed to replace older discrete solutions in high-performance timing applications.

Replacement Considerations

The 8V97051 is listed as Not Recommended for New Designs (NRND). The 8V97053L is a lower-power variant within the same family. Engineers transitioning from the 8V97051 should verify pin compatibility and register settings, as the 8V97053 offers improved phase noise performance.
