概述

The TPF1441C 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, TP1441C operates from a single 3.0V to 5.5V power supply.

TPF1441C integrates high-performance low-cost 72MHz 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. Moreover the filter can be bypassed to support wider bandwidth video application.

The TPF1441C’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 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.

TPF1441C is available in SOP-8 package (TPF1441C-SR) and MSOP-8 package (TP1441C-VR). Its operation temperature range is from −40°C to +85°C.
