The device in question is to replace an existing RF-to-baseband component of a geographically distributed signal collection system. Each receiving station samples the 6 MHz passband, detects a signal and estimates a time-of-arrival, then sends it on to a central facility that performs the multilateration calculations. The existing TOA codebase (and other decoders) expects 2 ns samples.
