June 1999 PRELIMINARY ML6423* Dual S-Video Lowpass Filter with Phase and Sinx/x Equalization GENERAL DESCRIPTION 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 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.
