Planar LC12 manual Timing and Frequency Video, Horizontal And Vertical Sync

physically connected to Signal Ground Reference (Pin 10) as defined by the wiring definitions of Table 2.

4.3Signal Quality

4.3.1TTL Sync Pulse Signal Levels

Input levels for the horizontal and vertical sync pulses are defined in Figure 8.

4.3.2Rise and Fall Times

Rise and fall times are the times required for signal transitions between 10% of Vs above Low Steady Level and 10% of Vs below High Steady Level where Vs is the peak-to-peak video input signal level. The overshoot, if present, shall be exempted from establishing these high/low levels referenced in. Both rise and fall times of each input signal shall be as follows:

Video:	Less than 5-ns
Horizontal Sync:	Less than 50-ns
Vertical Sync:	Less than 100-ns

4.4Timing and Frequency

4.4.1Video, Horizontal And Vertical Sync

Figure 6 illustrate video timing relationships the Monitor operates within when the specified video mode (per Table 3) is applied.

Front Porch defines the time from end of active video data to the start of Horiz/Vert Sync Pulse.

Back Porch defines the time from end of Horiz/Vert Sync Pulse to the start of active video data.

Blanking is the total time comprising Front Porch, Back Porch and Sync Pulse time(s).

The horizontal sync circuitry synchronizes to horizontal frequencies of 31.468 KHz ±0.5 KHz, 48.077KHz ±0.5KHz, and 56.476KHz ±0.5KHz. Horizontal sync pulse width variation is 1.813-µsec to 3.813-µsec. The Monitor will "sync" to the specified format vertical frequencies between 60Hz?72Hz without adjustment.

Absence of Horizontal and/or Vertical Sync will not damage the Monitor nor violate EMI radiation limits specified herein.
