Function
S-Bus Receiver Input
Differential inputs for the S-receiver.
Oscillator Input
Input pin of oscillator or input from external clock
source. 7.68 MHz crystal or clock required.
Oscillator Output
Output pin of oscillator. Not connected if external clock
source is used.
Clock Output
A 7.68 MHz clock is output to support other devices,
e.g. further IPACs in a multiline application. This clock
is not synchronous to the S interface.
Test Pins.
These pins are not used for normal operation.
They must be connected to GND.
