HDTV Anti-Aliasing Filters with Triple-Input Mux

2/MAX473

General Description

Features

The MAX7472/MAX7473 triple-channel anti-aliasing fil-

ters and buffers with triple-input mux are ideal for high-

definition (HD) and standard-definition (SD) television

(TV) applications. Compatible with 1080i, 720p, 480p,

and 480i scanning system standards as well as com-

puter format signals, the MAX7472/MAX7473 support

♦ Continuously Variable Anti-Aliasing Filter

5MHz to 34MHz in 256 Steps

♦ 3:1 Input Mux on Each Video Filter

♦ Supports All Standard Video and Computer Input

Formats

480i, 480p, 720p, 1080i

component video (Y P P , GsBR, and RGBHV) as well

QVGA, VGA, SVGA, XGA, SXGA, UXGA

as composite (CVBS) and S-video (Y/C).

Y P P , GsBR, RGBHV, Y/C, CVBS

The MAX7472/MAX7473 limit the input bandwidth for

anti-aliasing and out-of-band noise reduction prior to

digital conversion by an ADC or video decoder. The

frequency response of the MAX7472/MAX7473 can be

continuously varied in 256 linear steps from below SD

response to beyond HD response through an I²C inter-

face. The adjustable cutoff frequency allows filter opti-

mization for sampling rate and noise reduction. The

MAX7472/MAX7473 also include 3:1 multiplexers for

selection of three complete sets of video inputs through

the I²C interface.

♦ Accepts Any Input Sync Format

Sync on Y, Sync on G, External Sync

(Positive or Negative)

Sync on All Channels

♦ Buffered Outputs Drive Standard 150Ω Video Load

0dB (MAX7472)

+6dB (MAX7473)

♦ DC- or AC-Coupled Outputs

♦ Single +5V Analog and +3.3V Digital Supplies

♦ 5mW Power-Down Mode

♦ Lead (Pb)-Free 28-Pin TQFN Package

The MAX7472/MAX7473 drive a 2V

video signal into

P-P

a standard 150Ω load. The inputs are AC-coupled and

the outputs can be either DC- or AC-coupled. The

MAX7472 has a gain of 0dB and the MAX7473 has a

gain of +6dB. Both devices are available in a 28-pin

TQFN package and are fully specified over the upper-

commercial (0°C to +85°C) temperature range.
