General Description

The FMS6410 Dual Channel Video Filter – Driver Chip with CV Summer offers comprehensive video filtering for set top box or DVD applications. This part consists of two 4th order Butterworth 7.1MHz low pass filters for video signals. The filters are optimized for low overshoot and flat group delay. The device also contains a summing circuit to generate filtered composite video. Integrated video drivers are included to facilitate a direct drive to the outside world.
