8V97051NLGI Low Power Wideband Fractional RF Synthesizer

The design is comprised of 3 major parts. The first part consist of IDT8V97051NLGi wideband RF synthesizer/PLL supports the output frequencies with Voltage Controlled Oscillator (VCO). The temperature compensated crystal oscillator close to the RF input helps in the precision of signal while the other parts are filters that are used in various purposes like minimizing undesired noise. The second part consist of the USB 2.0 high speed to UART/FIFO IC that is used for system interface while the I2C-bus to SPI bridge IC controls the sequences, protocol, and timing of the signal. The last part is power supply management of the system in which it is provided with RC filters in every line to ensure minimal noise is included in the supply.

The design is applicable in multi-carrier, multi-mode FDD and TDD base station radio card. It optimized multi-service base stations during its service as a local oscillator that generates a large variety of frequencies to the mixers while maintaining excellent phase noise.
