Low Power Wideband Fractional RF Synthesizer / PLL
8V97053
Datasheet
General Description
The 8V97053 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 card. It is offered in a compact 5x5, 32-VFQFN.
The 8V97053 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 8V97053 with integrated Voltage Controlled Oscillator (VCO) 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 8V97053 is controlled by writing to registers through a 3-wire SPI interface. The 8V97053 also has an additional option that allows u.
