Product Summary
The NT68520XF is a high-quality image and highly integrated LCD controller, which combines triple video pre-amplifier, triple ADC, de-interlacing, YUV to RGB color space converter, scaling engine, gamma, OSD, and digital gain/offset, and supports analog RGB input, digital RGB input, and video CCIR656 8-bit input.The NT68520XF provides 64 RAM font and 128 ROM font that is very simply to create customer OSD. The NT68520XF supports single (24-bit) or dual (48-bit) pixel out format, and supports the 6-bit/color or 8-bit/color LCD panel. The built-in internal PLL locking to the reference clock generates all of the display timing to various LCD panels.
