PRODUCT OVERVIEW

The AD9864 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 AD9864 consists of a low noise amplifier (LNA), a mixer, a band-pass Σ-? analog-to-digital converter (ADC), and a deci mation filter with programmable decimation factor. An auto matic gain control (AGC) circuit gives the AD9864 12 dB of

continuous gain adjustment. Auxiliary blocks include both clock and LO synthesizers.
