The AD9874 is a general-purpose IF subsystem that digitizes a
low level 10 MHz to 300 MHz IF input with a signal bandwidth
ranging from 6.8 kHz to 270 kHz. The signal chain of the AD9874
consists of a low noise amplifier, a mixer, a band-pass sigma-delta
analog-to-digital converter, and a decimation filter with programmable
decimation factor. An automatic gain control (AGC) circuit
gives the AD9874 12 dB of continuous gain adjustment. Auxiliary
blocks include both clock and LO synthesizers.
