NOTES:
Notes 1 through 6 are applicable to the Receiver Differential Resistance
and Differential Capacitance specifications:
(1)
Specifications include both transmitter and receiver (tied together
internally).
(2)
Impedance parameters are specified directly between pins
TX/RX A(B) and TX/RX A(B) of the SSRT hybrid.
(3)
It is assumed that all power and ground inputs to the hybrid are con-
nected.
(4)
The specifications are applicable for both unpowered and powered
conditions.
(5)
The specifications assume a 2 volt rms balanced, differential, sinu-
soidal input. The applicable frequency range is 75 kHz to 1 MHz.
(6)
Minimum resistance and maximum capacitance parameters are
guaranteed over the operating range, but are not tested.
(7)
Assumes a common mode voltage within the frequency range of dc
to 2 MHz, applied to the pins of the isolation transformer on the stub
side (either direct or transformer coupled), and referenced to hybrid
ground. Transformer must be a DDC recommended transformer or
other transformer that provides an equivalent minimum CMRR.
(8)
An "X" in one or more of the product type fields indicates that the ref-
erence is applicable to all available product options.
(9)
MIL-STD-1760 requires an output of 20 Vp-p minimum on the stub
connection.
(10) External 10 F tantalum and 0.1 F capacitors to ground should be
located as close as possible to Pins 20 and 72, and a 0.1 F capac-
itor at pin 37.
(11) Power dissipation specifications assume a transformer coupled con-
figuration, with external dissipation (while transmitting) of 0.14 watts
for the active isolation transformer, 0.08 watts for the active bus cou-
pling transformer, 0.45 watts for each of the two bus isolation resis-
tors, and 0.15 watts for each of the two bus termination resistors.
(12) Measured from mid-parity crossing of command word to mid-sync
crossing of RT's status word.
