The TPF1441 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,
TP1441 operates from a single 3.0V to 5.5V power supply.
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 channel. 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 1080i/720p 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 consumption ,
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.
