The MAX9539/MAX9540 chipset provides a 3-wire

(RGB) interface for 5-wire (RGBHV) video by adding

and extracting the H, V, and composite sync from the

graphics video signals. This chipset eliminates the

problem of sync-to-video timing (skew errors) in a 5-

wire interface, while reducing the number of channels

required to transport video signals.

The MAX9539 mixes the H and V sync signals and

adds them to create a 3-wire interface from a 5-wire

(RGBHV) input. The MAX9540 recovers the H and V

sync signals to create a 5-wire (RGBHV) interface from

the 3-wire input. The MAX9540 also provides a com-

posite sync output.

The chipset includes the MAX9539 sync adder and the

MAX9540 sync extractor with 180MHz large-signal

bandwidths to address display resolutions up to 1600 x

1200 at 85Hz for VGA-to-UXGA applications. Both

devices feature a DC restore function, which virtually

eliminates any changes in black level. The chipset uses

a proprietary H and V sync addition/extraction scheme

(true sync) to minimize skew errors.

The MAX9539/MAX9540 are available in 28-pin TSSOP

packages and are specified over the extended -40°C to

+85°C temperature range.
