AMPLIFIER PAC, MODEL CM-033
The Sense Amplifier PAC, Model CM-033 (Figure A-70), contains two independent
sense amplifier channels which amplify the core outputs on memory sense lines and convert
the information content to µ-PAC logic levels.
Inputs to each channel are differential sig-
nals on twisted pair lines.
The information signals (measured differentially across pins
and 3 for one channel and 9 and 11 for the other) are approximately 50 mv in amplitude.
A strobe input is provided which, when grounded, disables the sense amplifier
channels.
Strobe enable inputs are provided to gate the strobe input of the channels.
An
amplifier will be enabled when both the strobe and strobe enable inputs are asserted at that
amplifier.
Both sense amplifier channels are provided with a direct output and a series 62-ohm
termination output.
The sense amplifier input ground return is generally connected to logic
ground.
