ML6424*/ML6425*

CCIR601 Video Lowpass Filter

with Optional Sinx/x Correction

GENERAL DESCRIPTION

FEATURES

The ML6424 is a monolithic BiCMOS Video Lowpass

Filter IC, incorporating a 5th order Elliptic (Cauer) lowpass

filter, a third order allpass filter, and a 75Ω coax cable

driver. The ML6425 additionally provides sinx/x amplitude

correction. These active lowpass filters are available with

a 2.75MHz (-2) or a 5.50MHz (-1) cutoff frequency.

■ External or internal input clamping with pulse output

for synchronous clamping of multiple filters

■ Frequency tunable with R : ±10%

EXT

■ ±0.25dB ripple

■ >40dB attenuation at f > 1.45 x f (w/o sinx/x)

■ >35dB attenuation at f > 1.45 x f (with sinx/x)

The input signal can be either AC or DC coupled under

the control of the MODE pin. In the DC coupled case, a

control pin (RANGE) is provided to allow the inputs to

swing down to ground. Internal self clamping is provided

for AC coupled signals.

■ –12dB attenuation at f = 1.23 x f

■ Group delay distortion: ±20ns up to 0.9 x f

■ <1% peak overshoot and ringing on 2T test pulse

■ 0.5% diff. gain and 0.5 diff. phase typical

■ THD <1% at 3.58 or 4.43MHz

The ML6424 and ML6425 are powered by a single 5V

supply, and can drive 1V into 75Ω (0.5V to 1.5V), or

■ Programmable input-output gain of 1x or 2x

2V into 150Ω (0.5 to 2.5V). The maximum output swing

from 0.5V to 2.5V allows easy interface to the ML6400

family of A/D converters.

■ 5V ±5% operation
