ML6421*

Triple Phase and Sinx/x Equalized,

Low-Pass Video Filter

GENERAL DESCRIPTION

FEATURES

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, or 3.0MHz bandwidth

■ 1x or 2x gain

■ 6th-order filter with phase and amplitude equalizer

■ >40dB stopband rejection

Cut-off frequencies are either 5.5, 8.0, or 3.0MHz. Each

channel incorporates a 6th-order lowpass filter, a first

order all-pass filter, a gain boost circuit, and a 75Ω 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.

■ No external components or clocks

■ ±10% frequency accuracy over maximum supply

and temperature variation

■ <2% differential gain <2° differential phase

■ <25ns group delay variation

The unity gain filters are powered from a single 5V supply,

■ Drives 1V into 75Ω, or 2V into 150Ω

P-P

and can drive 1V over 75Ω (0.5V to 1.5V), or 2V

P-P

■ 5V ±10% operation

over 150Ω (0.5V to 2.5V) with the internal coax drivers.
