High Performance Wideband Fractional RF Synthesizer / PLL

The 8V97053 is a high performance GSM1800 grade 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 package.

The 8V97053 Wideband RF Synthesizer / PLL offers a default  Fractional Mode with the option for an Integer mode. It requires an external loop filter.

The 8V97053 has an integrated Voltage Controlled Oscillator (VCO) and 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.
