19-0602; Rev 2; 1/07 KIT ATION EVALU E L B A IL AVA Graphics Video Sync Adder/Extractor General Description Features o 3-Wire RBG to 5-Wire RBGHV Interface o Supports VGA-to-UXGA Resolution o Low Offset Voltage (±1mV) o 180MHz Large-Signal Bandwidth MAX9539/MAX9540 www.datasheet4u.com 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 5wire 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 composite 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. Ordering Information PART MAX9539EUI+* MAX9539EUI MAX9540...
