BL-PQD140  Programmable Quad Display Controller

The PQD140 series allows the user to independently program the position and size of four windows within a single display. For each window, the X and Y position, X and Y size, layer priority, brightness, contrast, color, hue and more may be adjusted. This can result in images as simple as a dual or quad display to complex images made up of four differently sized and scaled layers from each of the four composite input signals.

Programming is accomplished via the RS232 control port. In a typical application, the unit would be driven by a custom software driver (user provided) however it can also be programmed in manual mode through an RS232 terminal or terminal application. Once the coefficients for each parameter are set, they can be saved to the internal EEPROM memory so the unit will always wake up to those settings. This works well for applications that do not need to change the window positions or sizes. Several pre-defined layouts can be selected. All parameters are programmed in hexadecimal with a simple code.

Facilities allow for simple selection of each channel for full display instead of the quad mode. The PQD140 can operate in either NTSC or PAL mode. Different coefficients are required for each due to the number of scan lines changing between systems.

The PQD140 is presently available as a board level product with the BL-PQD140-01 part number for OEM applications. We may produce a packaged version if there is enough interest in more than the board level product. Board level products do not include the power supply and a 5VDC regulated power source must be provided. The standard board level product with a -01 suffix includes the standard video connectors that the cased product uses. For OEM applications, we can provide units with header and other connection types. Custom designed or modified versions are also available. Minimum orders and or additional cost may apply for custom units. MicroImage Video Systems has designed many custom derivatives of standard products to meet the needs of different applications. We would be glad to help with your application. We have also provided product at the chip level. Quantity discounts are available.

The BL-PQD140-01 has a one year parts and labor limited warranty. Board level units are RoHS compatible and cased units are available as RoHS compatible.
