ML6426

High Bandwidth Triple Video Filters with Buffered

Outputs for RGB orYUV

GENERAL DESCRIPTION

FEATURES

The ML6426 are a family of triple video filters with

buffered outputs. There are several versions of the

ML6426, each with different passband cut-off frequencies

of 6.7MHz, 12MHz, 24MHz, 30MHz, 36MHz, and

■ 5V ±10% operation

■ RGB/YUV filters for ATSC Digital Television VESA

Standard

48MHz. Each channel contains a 4 -order Butterworth

lowpass reconstruction video filter. The filter is optimized

for minimum overshoot and flat group delay and

guaranteed differential gain and phase at the outputs of

the integrated cable drivers.

■ 2:1 Mux Inputs for multiple RGB/YUV inputs

■ Triple Reconstruction Filter options for 6.7, 12, 24, 30,

36, and 48MHz to handle various line rates

All input signals from DACs are AC coupled into the

ML6426. All channels have DC restore circuitry to clamp

the DC input levels during video H-sync, using an output

feedback clamp. An external H-sync signal is required for

this purpose.

■ Multiple ML6426 outputs can be paralleled to drive

RGB/YUV outputs at different frequencies for various

line rates by means of Disable/Enable pin.

■ 6dB drivers and sync tip clamps for DC restore

■ DC restore with minimal tilt

All outputs must be AC coupled into their loads. Each

output can drive 2V into a 150W load. All channels

P-P

have a gain of 2 (6dB) at 1V input levels.

■ 0.4% differential gain on all channels

0.4º differential phase on all channels

P-P

0.8% total harmonic distortion on all channels

■ 2kV ESD protection
