3 Description
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 Xband
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.
