Notes 1 through 6 are applicable to the Receiver Differential Input Impedance specifications:
1. Specifications include contributions from the transformer, transmitter, and receiver.
2. Impedance parameters are specified directly between pins CHA(B)_1553 and CHA(B)_1553_L of the Total-
AceXtreme hybrid.
3. It is assumed that all power and ground inputs to the package are connected.
4. The specifications are applicable for both unpowered and powered conditions.
5. The specifications assume a 2 volt rms balanced, differential, sinusoidal 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. Typical value for minimum Intermessage gap time. Under software control, this may be lengthened (to 65,535 µs -
message time) in increments of 1 μs.
8. In 0.5 μS increments with a resolution of ±12 μS.9. Measured from mid-parity crossing of Command Word to mid-
sync crossing of RT's Status Word.
9. MIL-STD-1760 requires a 20 V
PK-PK
minimum output on the stub connection.
10. Power supply cu
rrents and power dissipation assume nominal supply voltages, 1.8V and 3.3V. Power Dissipation is
the input power consumption minus the power delivered to the 1553 fault isolation resistors, bus termination
resistors, and the copper losses in the bus coupli
ng transformer. This power is assumed to be approximately 1.5
Watts when the Total-AceXtreme is transmitting.
11. See Section 9 for thermal management requirements at high transmit duty cycles
