8V97051

Low Power Wideband Fractional RF Synthesizer / PLL 8V97051 Datasheet Description The 8V97051 is a high-performance Wideband RF Synthesizer / PLL optimized for use as the local oscillator (LO) in Multi-Carrier, Multi-mode FDD, and TDD Base Station radio card. It is offered in a compact 5 5, 32-VFQFN package. The 8V97051 Wideband RF Synthesizer / PLL offers a default Fractional Mode with the option to use it with an Integer mode. It requires an external loop filter. The 8V97051 has an integrated Voltage Controlled Oscillator (VCO) that supports output frequencies from 34.375MHz to 4400MHz, and maintains superior phase noise and spurious performance. RF_OUT[A:B] output drivers have independently programmable output power ranging from –4dBm to +7dBm. The RF_OUT outputs can be muted. The mute function is accessible via a SPI command or mute pin. The operation of the 8V97051 is controlled by writing to registers through a three-wire SPI interface. The device also has an additional 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. In multi-service base stations, 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. The 8V97051 offers a large tuning range capable of providing multi-band local oscillator (LO) frequency synthesis in ...
