FMS6406CSX_NL - Precision S-Video Filter with Summed Composite Output/ Sound Trap/ and Group Delay Compensation

Description

The FMS6406 is a dual Y/C 5th order Butterworth lowpass video ﬁlter optimized for minimum overshoot and ﬂat group delay.

The device also contains a summing circuit to generate ﬁltered composite video, an audio trap and group delay compensation circuit.

Features

7.6MHz 5th order Y,C ﬁlters with composite summer.
14dB notch at 4.425MHz to 4.6MHz for Sound Trap capable of handling stereo.
50dB stopband attenuation at 27MHz on Y, C and CV outputs.
Better than 0.5dB ﬂatness to 4.2MHz on Y, C and CV outputs.
Equalizer and notch ﬁlter for driving RF modulator with group delay of -180ns.
No external frequency selection components or clocks.
< 5ns group delay on Y, C and CV outputs.
AC cou.
