Data Sheet IF Digitizing Subsystem AD9864 FEATURES GENERAL DESCRIPTION 10 MHz to 300 MHz input frequency 6.8 kHz to 270 kHz output signal bandwidth 7.5 dB single sideband noise figure (SSB NF) −7.0 dBm input third-order intercept (IIP3) AGC free range up to −34 dBm 12 dB continuous AGC range 16 dB front-end attenuator Baseband I/Q 16-bit (or 24-bit) serial digital output LO and sampling clock synthesizers Programmable decimation factor, output format, AGC, and synthesizer settings 370 Ω input impedance 2.7 V to 3.6 V supply voltage Low current consumption: 17 mA 48-lead LFCSP package APPLICATIONS The AD98641 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 decimation filter with programmable decimation factor. An automatic gain control (AGC) ...
