The AD9864 is a general-purpose IF subsystem that digitizes a low level 10 MHz to 300 MHz IF input with a signal bandwidth of 6.8 kHz to 270 kHz.
The AD9864 is a general‑purpose narrow‑band IF subsystem that digitizes a low‑level 10 MHz to 300 MHz input with a signal bandwidth of 6.8 kHz to 270 kHz. It integrates a low‑noise amplifier, mixer, band‑pass Z‑A ADC, and a programmable decimation filter, and includes on‑chip LO and clock synthesizers as well as automatic gain control.
The device operates from a single 2.7 V to 3.6 V supply, consumes about 56 mW in normal mode, and is offered in a 48‑lead LFCSP package. Detailed pin descriptions, absolute maximum ratings, thermal resistance, and ordering information are provided throughout the document.
