72M HD Composite Video Filter Driver with Clamped input Comparator

Feartures

Description



Wide Power Supply: +3.0V to +5.5V Single Supply

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 PUSH-

PULL output supports rail-to-rail output swing, and interfaces

with CMOS/TTL logic.
