ADD 1.7 - Manual
3.3 Schematic Layout and Device Functioning
The 16-fold frequency divider has a BNC connector for the input signal which must be a low voltage (LV)TTL,
but is TTL tolerant. The frequency of the input signal is divided by a frequency dividing factor and is given out
on three BNC connectors which are connected via a 3-fold FAN OUT. The output signal is a LVTTL signal
again.
The frequency dividing factor can be switched between 1 (OFF) and 16 (ON).
The schematic layout of the ADD 1.7 is given below in Figure 2.

3.4 Power Supply
The operation power for the ADD 1.7 is +5V. It is provided via a wall power supply. Connect the wall power
supply to the round 5pin socket named “power” of the ADD 1.7. The pin configuration of the 5pin socket is
shown below in Figure 3.
