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 Mark3 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 a 20 Vp-p minimum output on the stub con-
nection.
(10) External 10 F tantalum and 0.1 F capacitors to ground should be
located as close as possible to +3.3 Vdc input pins.
(11) Power dissipation is the input power minus the power delivered to
the 1553 fault isolation resistors, the power delivered to the bus ter-
mination resistors, and the copper losses in the transceiver isolation
transformer and the bus coupling transformer. An illustration of exter-
nal power dissipation for transformer coupled configuration (while
transmitting) is: 0.14 watts for the active isolation transformer, 0.08
watts for the active bus coupling transformer, 0.45 watts for each of
the two bus isolation resistors 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.
(13)
θJC is measured to bottom of ceramic case.
(14) Current drain and power dissipation specifications are based on a
small sample size and subject to change.
