description
The TVP3703 is a super video graphics array (SVGA) compatible, true-color CMOS RAMDAC with integrated
clock synthesizers that can provide the memory and pixel clock signals for a PC graphics subsystem. The video
clock can be one of two VGA base frequencies or fourteen Video Electronics Standards Association (VESA)
standard frequencies which can also be reprogrammed through the standard micro port interface.
The memory clock output is also user programmable at frequencies up to 80 MHz. The pixel modes supported
by the TVP3703 include:
• Serializing 16-bit pixel port providing 170 MHz, 8-bit and 73 MHz, 24-bit packed pixel modes using an
internal PLL
• 16-bit pixel port providing faster, high-color/true-color operation up to the 110 MHz sampling rate
• 8-bit pixel port providing standard SVGA and high-color/true-color modes up to the 110 MHz sampling rate
The 68 terminal FN package is designed to be interchangeable with the STG1703.
