ML6420

FUNCTIONAL DESCRIPTION

The ML6420 single-chip Dual/Triple Video Filter ICs are

intended for low cost professional and consumer video

applications. Each channel incorporates an input buffer

amplifier, a sixth order lowpass filter, a first order allpass

equalizer, and an output 1X or 2X gain amplifier capable

of driving 75

W to ground.

When RANGE is low the input and output signal range is

0.5V to 1.5V. When the input signal range is 0V to 1V,

RANGE should be tied high. In this case, an offset is added

to the input so that the output swing is kept between 0.5V

to 1.5V. The output amplifier is capable of driving up to

24mA of peak current; therefore the output voltage should

not exceed 1.8V when driving 75

W to ground. The

ML6420 can be driven by a DAC with swing down to 0V.

The summer output on the ML6422 is given by 2x(VINA +

VINC) – 2.5V when RANGE = 0 and 2x(VINA + VINC) –

0.5V when RANGE is high. So, VINA and VINC should be

such that this output does not go below 0.5V or above

2.5V for proper operation.
