TW9984 also includes an ntsc/pal video encoder with a 10-bit dac to support cvbs output. related literature ? ug018, ?TW9984at-na1-ge-eval evaluation board user guide? features ? accepts all ntsc (m/4.43)/pal (b/d/g/h/i/k/l/m/n/60)/ secam standards with auto detection ? integrated four video analog antialiasing filters and 10-bit cmos adcs with differential and single-ended inputs ? high performance adaptive 4h comb filters for all ntsc/pal standards ? if compensation filter for improvement of color demodulation ? color transient improvement (cti) ? automatic white peak control ? programmable hue, saturation, contrast, brightness and sharpness ? proprietary fast video lock ing system for non-real-time application ? supports the standard itu-r bt.656 format or time multiplexed output with 54/108mhz ? supports a two-wire serial host interface ? integrated video encoder and 10-bit video cmos dac ? integrated clock pll for 108mhz clock output ? short-to-battery, short-to-ground detection ? ultra low power consumption (typical 550mw) ? single 27mhz crystal for all standards and output options ? 1.2v/3.3v power supply ? optional 1.8v operation of digital output ? 10mmx10mm 68 ld wqfn package ? aec-q100 qualified figure 1.
