8V97051A Datasheet | Renesas

Description The 8V97051A 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 pact 5 5, 32-VFQFPN package. The 8V97051A 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 8V97051A 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 - 4d Bm to +7d Bm. The RF_OUT outputs can be muted. The mute function is accessible via a SPI mand or mute pin. The operation of the 8V97051A 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 patible 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 8V97051A offers a large tuning range capable of providing multi-band local oscillator (LO) frequency synthesis in multi-mode base stations, thus limiting the use of multiple narrow band RF Synthesizers and reducing the BOM plexity and cost. The device can operate over -40°C to +85°C industrial temperature range.
