RF SPECTROMETER (P19800B)

The P19800B spectrometer ASIC processes up to 5.5GHz bandwidth input signals provided by microwave front ends. The ASIC includes a VGA, a 6-bit ADC, an FFT based on polyphase filtering and an accumulator capable of accumulating up to 34 seconds of frequency-domain data. The chip also includes an output data interface, a PLL based frequency synthesizer and a SPI interface for the ASIC’s programming and data interchange at low speed. The chip is offered in a BGA package and as an IP block for integration into SoCs. The P19800B ASIC is also offered on an evaluation board.
