1.0 Description
The PD-15RMi-C is a TTL Pulse Distribution Amplifier that provides distribution for 1 PPS
signals.
The PD-15RMi-C has three inputs which drive three distribution modules. Each module
supplies five buffered outputs designed to drive low impedance loads and long 50 or 75
ohm cables. The outputs provide a 3.7 volt peak-to-peak signal into a 50 ohm load. The
channel-to-channel delay differences are typically 100 ps. The distribution modules have
typically 3 ps/ºC temperature coefficient of propagation delay that is essential for the
distribution of high quality timing signals.
This instrument is designed to be powered by a 100 to 240 VAC mains source or by a
+12 to +36 VDC power source. If both AC and DC sources are powering the instrument,
the DC source will be used as backup power in case of AC power outages. The
instrument is designed to automatically switch from AC to DC supply operation using a
Schottky diode network and charge storage capacitors to avoid any glitches and ensure
uninterrupted continuous operation.
