The 8V97052 is a high performance wideband RF synthesizer / PLL optimized for use as the local oscillator (LO) in multi-carrier, multi-mode FDD & TDD base station radio cards. It is offered in a compact 5x5, 32-VFQFN package.

The 8V97052 wideband RF synthesizer / PLL offers a default fractional mode with the option for an Integer mode. It requires an external loop filter. The 8V97052 can operate with either on-chip voltage-controlled oscillator (VCO) or external VCO to provide a low jitter output that is locked to an external reference.

The 8V97052 has an integrated VCO and supports output frequencies from 34.375MHz to 4400MHz and maintains superior phase noise and spurious performance.

RF_OUT output driver has independently programmable output power ranging from –4dBm to +11.5dBm. The RF_OUT output can be muted. The mute function is accessible via a SPI command or mute pin.
