1.Product Specification (continued)
1.3.1.3Audio Jack (option)
Thisjack shall connect the audio input from
hostcomputer.
1.3.2 Video Input Signals
Video Input Signal Ranges
1.3.2.1 Video Signal Amplitudes
The three video inputs consist of Red ,Green , and Blue
signals, each with its own coaxial cable terminated at the
monitor. These video signals are analog levels, where 0
V corresponds to black , and 700 mV is the maximum
signal amplitude for the respective color, when each
signal is terminated by a nominal 75.0 ohms .For a given
monitor luminance levels are measured using this
defined video amplitud driving a monitor meeting the
termination requirements .The signal amplitude is not to
be readjusted to compensate for variations in termination
impedance.
1.3.2.2 Video Signal Termination Impedance
This analog video signal termination shall be 75 1%
which shall be resistive with a negligible reactive
component
1.3.2.3 Synchronization ( Sync ) Signals
The Horizontal Sync (HS) TTL signal is used to initiate
the display of a horizontal line. HS may be either active
high or active low, depending upon the timing .The
Vertical Sync (VS) TTL signal is used to initiate the
display of a new frame .VS may be either active high or
active low, depending on the timing
1.3.2.4 Sync Signal Levels
The monitor must accept sync signals from both 3.3 and
5 volt TTL logic families.The inputs shall sense a logic 0
when the input is 0.8 volt or less and shall sense a logic
1 when the input is 2.0 volts or greater. In addition to
these level requirements, there shall also be a minimum
of 0.3 volt hysteresis provided for noise immunity
(typically by using a Schmitt Trigger input ).That is , the
input level at which the monitor actually detects a logic 0
shall be at least 0.3 volt lower than the level at which it
actually detects a logic 1.If the monitor sync processing
circuits are designed around the 3.3 volt logic family
,then the sync inputs must be 5 volt tolerant .
