The AFE7906 is a high performance, wide bandwidth multi-channel receiver, integrating six RF Sampling ADCs. With operation up to 12 GHz, this device enables direct RF sampling in the L, S, C and X-band frequency ranges without the need for additional frequency conversions stages. This improvement in density and flexibility enables high-channel-count, multi-mission systems.

Each receiver chain includes a 25-dB range DSA (Digital Step Attenuator), followed by a 3-GSPS ADC (analog-to-digital converter). Four receiver channels have an analog peak power detector and various digital power detectors to assist an external or internal autonomous automatic gain controller, and RF overload detectors for device reliability protection. Flexible decimation options provide optimization of data bandwidth up to 1200 MHz for four RX or 600 MHz.

The device contains a SYSREF timing detector to allow optimization of the SYSREF input timing relative to the device clock.
