Description
The 8V97053L is a high-performance GSM1800 grade wideband RF synthesizer/PLL optimized for use as the local oscillator (LO) in multi-carrier, multi-mode FDD and TDD base station radio cards. It is offered in a compact 5mm x 5mm, 32-VFQFN package.
The 8V97053L wideband RF synthesizer/PLL offers a default Fractional mode with the option for an Integer mode. It requires an external loop filter.
The 8V97053L has an 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 an SPI command or mute pin.
