Electrical Signals
The RF, IF and AUX inputs to the RX-1 are 50 ohm interfaces.
The IF outputs are also 50 ohms.
The impedance of the video outputs can be switched to 50 ohms, 75 ohms or low impedance.
Polarity can be reversed and coupling can be switched from AC to DC.
The AGC and AM interfaces are low impedance. Their polarity can be reversed. The AM output can
be delayed to fit the tracking loop.
The Clock and Data TTL outputs are 50 ohms, but they can fit 75 ohms interfaces. Their polarity can
be reversed. The clock phase can be adjusted from 90° steps, as shown on the following figure:
0 degree clock:
data valid on falling edge
90 degree clock:
data valid in middle
180 degree clock:
data valid on rising edge
270 degree clock:
data valid in middle
double-data rate clock:
data valid on both rising
and falling clock edges
