NT68520X,E
GENERAL DESCRIPTION
The NT68520 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 video amplifier supports a full scale range of 0.5 ~ 1Vp-p with 0.8 ~ 2X gain and also
provides a DC offset adjustment.
The ADC supports up to 135MHz pixel rate and build in a low jitter PLL to sampling input
video that provides a low-noise and more stabile image quality.
The NT68520 also builds in a DSP engine to execute linear zoom-in, zoom-out function
of image to fit different panel resolutions.
The OSD provides 64 RAM font and 128 ROM font that is very simply to create customer
OSD.
The display interface 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.
