1 / 47 page  Datasheet R31DS0022EU0110 Rev.1.1 Page 1 Feb 6, 2023 © 2021 Renesas Electronics The 8V97052 is a high-performance wide-band RF synthesizer / PLL that offers a high resolution of 32-bit fractional and modulus. It is ideal for use in instrumentation, test equipment, satellite equipment, or applications that require very fine adjustments of the output frequency. It is also optimal for use as a traditional Local Oscillator (LO) in Multi-Carrier, Multi- mode FDD, and TDD Base Station radio card. The 8V97052 offers an integrated Voltage Controlled Oscillator (VCO) and output divider that supports a continuous output frequency range of 34.375MHz to 4400MHz. This large frequency tuning range can provide multi-band local oscillator (LO) frequency synthesis, thus, limiting the use of multiple narrow band RF synthesizers and reducing the BOM complexity and cost. The RF_OUT output driver has an independently programmable output power ranging from -4dBm to +11.5dBm. The RF_OUT output can be muted via a SPI command or mute pin. Integrated low noise Low Dropout Regulators (LDOs) are used for superior power supply noise immunity. The operation of the 8V97052 is controlled by writing to registers through a 3-wire SPI interface. The device also has an option that allows users to read back values from registers by configuring the MUX_OUT pin as a SDO for the SPI interface. The SPI interface is compatible with 1.8V logic and tolerant to 3.3V. The device also includes features such as fast lock, programmable charge pump current, electable DSM types and orders, output mute, lock detection, MUX_OUT, and phase adjust that can help with specific system requirements, optimization, or power savings. In RF applications, very low noise oscillators are required to generate a large variety of frequencies to the mixers while maintaining excellent phase noise performance and low power.
