The ML6423 monolithic BiCMOS 6th-order filter provides a two-channel fixed frequency lowpass filtering for video applications. This dual phase equalized filter with sinx/x correction is designed for reconstruction filtering at the output of a Video DAC. A composite sum output of ML6423 eliminates the need for a third DAC.

Cutoff frequencies are either 5.5MHz or 9.6MHz. Each channel incorporates a 6th-order lowpass filter, a first order allpass filter, a gain boost circuit, and a 75W coax cable driver. A control pin (RANGE) is provided to allow the inputs to swing from 0 to 1V, or 0.5 to 1.5V, by providing a 0.5V offset to the input.

The 2X gain filters ML6423 are powered from a single 5V supply, and can drive 1VP-P into 75W (0.5V to 1.5V), or 2VP-P into 150W (0.5V to 2.5V) with the internal coax drivers.
