The TP1441 is a low power, 72M HD composite video filter and comparator on a single chip. Drawing less than 11.5mA supply current over the full operating temperature range, the TP1441 operates from a single 3.0V to 5.5V. TPF1441 integrate high-performance low-cost 72MHz composite video reconstruction filter, it combine excellent video performance and low power consumption perfectly. It incorporates one high-definition (HD) filter channels. The filter feature 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 be bypassed to support HDCVI 1080p/60 video. The TPF1441’s on-board comparator incorporates 3PEAK’s proprietary and patented design techniques to achieve the ultimate combination of high-speed (68ns propagation delay under 3.0~5.5V wide supply range) and low power consuming, The internal input hysteresis eliminates output switching due to internal input noise voltage, reducing current draw. The push-pull output supports rail-to-rail output swing, and interfaces with CMOS/TTL logic. TPF1441 is available in SOP-8 package (TPF1441-SR). Its operation temperature range is from −40° C to +85° C.
