Descrription

_______________

The MSVL14 provides a fourth-order video Lowpass

Butterworth response filter with a corner at 14 MHz

for use in Luminance filtering in HDTV or other higher

resolution video systems. The MSVL14 is a continuous

time filter with greater than 3% accuracy.

Unlike digital filters or other sample data filters, the

MSVL14 does not use a sampling clock.

The filter’s

corner frequency is set by internal capacitors and resis-

tors.

Only decoupling capacitors on the supplies and

a bias resistor to set the operating current are needed

to operate the MSVL14.

The elimination of clocking reduces noise generated by

the clock as well as reduces distortion.

The MSVL14 is available in a 16-Pin 150 mil SOIC.
