DisplayPort-To-VGA Conversion Chip Supports High Resolutions

May 5, 2014
A DisplayPort receiver/VGA transmitter developed by Chrontel offers a compatible bridge to the huge installed base of legacy video-graphics-array (VGA) displays.

A DisplayPort receiver/VGA transmitter developed by Chrontel offers a compatible bridge to the huge installed base of legacy video-graphics-array (VGA) displays. The CH7517 converts standard DisplayPort video signals generated by a CPU or GPU into the analog VGA format widely used by external displays. It complies with DisplayPort v1.2 and embedded DisplayPort v1.3, and supports Video Electronics Standards Assocation (VESA) and Consumer Electronics Association (CEA) resolutions up to 1920 by 1200 at 60 Hz. Three 9-bit digital-to-analog converters (DAC) generate analog RGB signals, an internal extended display identification data (EDID) buffer, and on-chip flash boot ROM for initialization. The device can perform automatic DisplayPort input detection and DAC output detection, enabling autonomous entry to power-saving mode. All CH7517s come in 40-pin QFN packaging.
