ML6420CS-3

September 1999 PRELIMINARY ML6420* Triple/Dual Phase-Equalized, Low-Pass Video Filter GENERAL DESCRIPTION The ML6420 monolithic BiCMOS 6th-order filters provide fixed frequency low pass filtering for video applications. These triple output phase-equalized filters are designed for input anti-aliasing filtering. Cut-off frequencies are either 3.0, 5.5, 8.0, or 9.3MHz. Each channel incorporates a 6th-order low-pass filter, a first order all-pass filter, and a 75W coax cable driver. A control pin (Range) is provided to allow the inputs to swing to ground by providing a 0.5V offset to the input. The filters are powered from a single 5V supply, and can drive 1VP-P over 75W (0.5V to 1.5V), or 2VP-P over 150W (0.5V to 2.5V).
