4 Description (continued)

Each receiver chain includes a 25 dB range DSA (Digital Step Attenuator), followed by a 3 GSPS ADC (analog-

to-digital converter). Each receiver channel has 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 400 MHz

for two RX.

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

device clock.
