Fig. 1 Functional Block Diagram

The ASNT_28_1 system on board functions as a multi-purpose divider for test, prototyping, microwave, and communication applications. There are two differential outputs present; a fixed div/4, and a selectable 1-to-512 divide ratio. All inputs and outputs are AC coupled. The input waveform can be single-ended or differential. High-speed SMA connectors are installed for inputs and outputs. The selectable divide output can be operated single-ended or differentially. Power is supplied through a two pin MOLEX connector.


The ASNT_28_1 divider can be used as a prescaler to extend the useful frequency range for triggering. The second fixed div/4 output can be used to synchronize other devices. The divider can be used in a divide-by-1 mode to buffer low amplitude signals, or provide a differential output from a single-ended signal. The divider can also be used as a prescaler for PLL’s or frequency counters.
