Overview

The AD9864BCPZRL is a general-purpose IF subsystem that digitizes alow level, 10 MHz to 300 MHz IF input with a signal bandwidthranging from 6.8 kHz to 270 kHz. The signal chain of the AD9864consists of a low noise amplifier (LNA), a mixer, a band-pass Σ-∆analog-to-digital converter (ADC), and a decimation filter withprogrammable decimation factor. An automatic gain control(AGC) circuit gives the AD9864BCPZRL 12 dB of continuous gainadjustment. Auxiliary blocks include both clock and localoscillator (LO) synthesizers.

The AD9864BCPZRL is available in a 48-lead LFCSP package and operatesfrom a single 2.7 V to 3.6 V supply. The total power consumptionis typically 56 mW and a power-down mode is provided viaserial interfacing.
