PRELIMINARY  
ML6421  
Triple Phase and Sinx/x Equalized,  
Low-Pass Video Filter  
FEATURES  
GENERAL DESCRIPTION  
The ML6421 monolithic BiCMOS 6th-order filter provides  
fixed frequency low pass filtering for video applications.  
This triple phase-equalized filter with Sinx/x correction is  
designed for reconstruction filtering at the output of a  
Video DAC.  
5.5, 8.0, 9.3, 3.0, 1.8 or 2.5MHz bandwidth  
1x or 2x gain  
6th-order filter with phase and amplitude equalizer  
>40dB stopband rejection  
No external components or clocks  
Cut-off frequencies are either 5.5, 8.0, 3.0 or 1.8MHz.  
Each channel incorporates a 6th-order lowpass filter, a first  
order all-pass filter, a gain boost circuit, and a 75ý 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.  
±10% frequency accuracy over maximum supply  
and temperature variation  
<2% differential gain <2° differential phase  
<25ns group delay variation  
Drives 1V into 75, or 2V into 150Ω  
The unity gain filters are powered from a single 5V supply,  
P-P  
P-P  
and can drive 1V over 75ý (0.5V to 1.5V), or 2V  
P-P  
P-P  
5V ±10% operation  
over 150ý (0.5V to 2.5V) with the internal coax drivers.
