Overview

Input Capacitance
The input capacitance at the RIN pin is typically 2.8 pF
(SOJ package) and 3.6 pF (DIP package).
Cable Loss Characteristics
The signal at the cross connect may travel through a
distribution frame, coaxial cable, connectors, splitters,
and backplanes before reaching the T7295-6 device.
This section defines the maximum distribution frame
and cable loss from the cross connect to the T7295-6
input.

Figure 9. Loss Characteristic of 728A Coaxial Cable
(450 ft.)
The distribution frame jack may introduce 0.6 dB
±
0.55 dB of loss. This loss may be any combination of
flat or shaped (cable) loss.
The maximum cable distance between the point where
the transmitted signal exits the distribution frame jack
and the T7295-6 device is 450 ft. (see Figure 3). The
coaxial cable (Type 728A) used to specify that this dis-
tance limitation has the loss and phase characteristics
shown in Figure 9 and Figure 10. Other cable types
also may be acceptable if distances are scaled to main-
tain cable loss equivalent to Type 728A cable loss.
