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