IN1401 Operation Manual - v1.5 7/12/02 11:18 AM
LOW POWER SLEEP MODE
If no input signal is detected, the IN1401 will enter a low power sleep mode operation.
During this mode, the processor is still active and will continue to monitor the input for any
video signal. Upon connection to the video signal, the IN1401 will automatically return to its
normal mode of operation. The IN1401 menu may be displayed and adjusted without any
video signal connected. If the IN1401 is in its low power mode, press menu or enter to turn
on the unit and start the menu. All controls are available. The background will be blue if no
signal is present and cannot be turned off until a signal is connected. Upon exiting the menu,
the IN1401 will again return to its low power mode if no signal is present.
MAXIMUM INPUT AND OUTPUT MODES
There are six factors that limit the input and output modes of the IN1401:
1. Input Active Pixels
≤
Output Active Pixels
2. Input Active Lines
≤
Output Active Lines
3. Input Pixel Clock
≤
95 MHz (After De-Interlacing)
4. Intermediate Pixel Clock
≤
95 MHz (After Frame Rate Conversion)
5. Output Pixel Clock
≤
135 MHz (After Image Scaling)
6. (Input Pixel Clock + 95) / 1.8
≤
95 (Bandwidth Formula)
LIMITATIONS OF SETTINGS
The following criteria must be met for all signals. Any attempt to adjust the settings beyond
these criteria results in an invalid video signal and will not be allowed. If any setting will not
move to the desired value, verify the equations below and refer to the list of problems /
solutions on page 17 of the Troubleshooting Section to find the alternate setting required.
Input Total Pixels

In addition to the above limitations, the predefined input modes only have a full range of 256
units. If a setting /- 128 units from the default value is desired, the user-defined
mode may be selected.
Note: All of the limits listed above apply to the user-defined mode.
