Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
DisplayPort 1.3 raises that to 32.4 Gbit/s (25.92 Gbit/s with overhead removed), and HDMI 2.1 raises that up to 48 Gbit/s (42.67 Gbit/s with overhead removed), adding an additional TMDS link in place of clock lane. DisplayPort also has the ability to share this bandwidth with multiple streams of audio and video to separate devices.
Some manufacturers released some 4000-series equivalent CMOS circuits with a 74 prefix, for example, the 74HC4066 [2] was a replacement for the 4066 with slightly different electrical characteristics (different power-supply voltage ratings, higher frequency capabilities, lower "on" resistances in analog switches, etc.).
The Mini DisplayPort (MiniDP or mDP) is a miniaturized version of the DisplayPort audio-visual digital interface. It was announced by Apple in October 2008, and by early 2013 all new Apple Macintosh computers had Mini DisplayPort, [ 2 ] as did the LED Cinema Display .
Consumer Electronics Control (CEC) is a feature of HDMI designed to control HDMI connected devices [1] [2] by using only one remote controller; so, individual CEC enabled devices can command and control each other without user intervention, for up to 15 devices.
A notable example of a display driver IC is the Hitachi HD44780 LCD controller. Other controllers are KS0108, SSD1815 (graphics capable) and ST7920 (graphics capable) Other controllers are KS0108, SSD1815 (graphics capable) and ST7920 (graphics capable)
Metcalfe subsequently co-founded 3Com in 1979. [1] The other co-founders were Metcalfe's college friend Howard Charney and two others. [1] Bill Krause joined as President in 1981 and became CEO in 1982 and led 3Com until 1992 when he retired. 3Com began making Ethernet adapter cards for many early 1980s computer systems, including the DEC LSI-11, DEC VAX-11, Sun-2 and the IBM PC.
A tray of application-specific integrated circuit (ASIC) chips A packet processing ASIC inside an Ethernet switch An application-specific integrated circuit ( ASIC / ˈ eɪ s ɪ k / ) is an integrated circuit (IC) chip customized for a particular use, rather than intended for general-purpose use, such as a chip designed to run in a digital ...
