GENERAL DESCRIPTION

The ML6426 are a family of triple video filters with buffered outputs. There are several versions of the ML6426, each with different passband cut-off frequencies of 6.7MHz, 12MHz, 24MHz, 30MHz, 36MHz, and 48MHz. Each channel contains a 4th-order Butterworth lowpass reconstruction video filter. The filter is optimized for minimum overshoot and flat group delay and guaranteed differential gain and phase at the outputs of the integrated cable drivers.

FEATURES

■ 5V ±10 operation

■ RGB/YUV filters for ATSC Digital Television VESA Standard
