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 PCI Enhanced Mini-ACE hybrid.
(3)
It is assumed that all power and ground inputs to the hybrid 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)
Assumes a common mode voltage within the frequency range of dc to 2
MHz, applied to pins of the isolation transformer on the stub side (either
direct or transformer coupled), and referenced to hybrid ground.
