Low Power IF Digitizing Subsystem

The AD9874 is a general purpose IF subsystem that digitizes a low level 10-300MHz IF input signal with a bandwidth of up to 270 kHz. The signal chain of the AD9874 contains a low-noise Amplifier mixer, a band pass sigma-Delta Analog-to-digital converter and a decimation Filter with programmable decimation factor. An Automatic gain control (AGC) circuit provides the AD9874 with 12 dB of continuous gain adjustment
The high dynamic range and inherent anti-aliasing provided by the bandpass sigma delta converter allows the AD9874 to cope with blocking signals 95 dB stronger than the desired signal. Auxiliary blocks include Clock and LO synthesizers in addition to a serial peripheral Interface port.
