The TPF1441NC is a low power, 52M HD composite video filter and comparator on a single chip. Drawing less than 11.5mA supply current over the full operating temperature range, TP1441NC operates from a single 3.0V to 5.5V power supply. TPF1441NC integrates high-performance low-cost 52MHz composite video reconstruction filter, however it has very low power consumption. The filter is sixth-order Butterworth characteristics that are useful as digital-to-analog converter (DAC) reconstruction filters or as analog-to-digital converter (ADC) anti-aliasing filters. The HD filters can actually support 720p/1080p CVI/TVI/AHD platform. The TPF1441NC’s on-board comparator incorporates 3PEAK’s proprietary and patented design techniques to achieve the ultimate combination of high-speed (40ns propagation delay under 3.0~5.5V wide supply range) and low power consumption , The internal input hysteresis eliminates output switching due to internal input noise voltage, reducing current draw. The PUSHPULL output supports rail-to-rail output swing, and interfaces with CMOS/TTL logic. TPF1441NC is available in MSOP-8 package (TP1441NCVR). Its operation temperature range is from −40°C to +85°C.
