AM and TTL Outputs

The PTP card provides AM (Amplitude Modulated) and TTL (Transistor-Transistor
Logic) outputs.
The AM OUT port supports the IRIG-B AM signal format, while the TTL OUT port
supports the IRIG-B PWM and PPS signal formats. Enabling/disabling the output ports
and – in the case of TTL OUT – selecting the signal format is controlled through the
RUGGEDCOM RSG2288 operating system.
The input impedance of third-party AM inputs must be 100 Ω minimum.
The number of devices that can be connected to the AM OUT and TTL Out ports is
dependent on the cabling type and length, as well as the input impedances of the
devices. The following simplified circuit schematic shows the interface between an
IRIG-B source and connected devices.
