Triple/Dual Phase-Equalized, Low-Pass Video Filter
1
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 1V
P-P
over 75W (0.5V to 1.5V), or 2V
P-P
over 150W
(0.5V to 2.5V).
