MHL Switch Transfers HD Audio/Video At 1.3 GHz

The NCN1188 debuts as the first mobile high-definition link (MHL) switch supporting both high definition video and audio data transfers at speeds up to 1.3 GHz. A 3:1 high speed USB switch with integrated MHL support, the switch allows smartphones and other portable consumer electronics to interface with HD TVs. The device exploits two dedicated data paths handling HD video transfers up to 720 progressive scan at 60 fps and 1080 interlaced at 30 fps plus a multi-purpose audio path with true-ground capability down to -2V that supports generic micro-USB headsets. Specs include an operating voltage range of 2.7V to 5.5V, current draw of 23 mA, typical on capacitance of 4.5 pF, typical off capacitance of 3 pF, and an operating temperature range from -40°C to +125°C. Available in a 12-pin UQFN package measuring 2 mm x 1.7 mm x 0.5 mm, pricing for the NCN1188 is $0.45 each/10,000. ON SEMICONDUCTOR, Phoenix, AZ. (800) 282-9855.
