The AD9864 is a general-purpose IF subsystem that digitizes a low level 10 MHz to 300 MHz IF input signal. It has a wide range of applications, including multimode narrow-band radio products, analog/digital UHF/VHF FDMA receivers, TETRA, APCO25, GSM/EDGE portable and mobile radio products, and SATCOM terminals.
The AD9864 is a general‑purpose narrow‑band IF subsystem that digitizes a low‑level 10 MHz to 300 MHz input with a selectable 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.
Key features include a 2.7 V–3.6 V supply range, low 17 mA current consumption, 48‑lead LFCSP packaging, and a programmable decimation factor from 48 to 960. The device offers up to 95 dB dynamic range with AGC enabled and supports both 16‑bit and 24‑bit I/Q digital outputs via a synchronous serial interface.
