Data Carrier Detect (DCD) or Carrier Detect (CD) is a control signal present inside an RS-232 serial communications cable that goes between a computer and another device, such as a modem. This signal is a simple "high/low" status bit that is sent from a data communications equipment (DCE) to a data terminal equipment (DTE), i.e., from the modem ...
In simple terms, the transmitter circuit must output a signal with a minimum of 600 mV peak-to-peak differential, maximum 2000 mV peak-to-peak differential. A good signal looks rather like a sine-wave with a fundamental frequency of half the data rate, so 1 GHz for a typical system running at 2 gigabits per second.
Schematic of a TMDS link used as a link for digital component video data (RGB) between a video controller (PC) and a display controller (Monitor) in interfaces such as DVI or HDMI Transition-minimized differential signaling ( TMDS ) is a technology for transmitting high-speed serial data used by the DVI [ 1 ] and HDMI video interfaces, as well ...

In addition to digital, some DVI connectors also have pins that pass an analog signal, which can be used to connect an analog monitor. The analog pins are the four that surround the flat blade on a DVI-I or DVI-A connector. A VGA monitor, for example, can be connected to a video source with DVI-I through the use of a passive adapter. Since the ...

The second byte is an opcode which specifies the operation to be performed, and the number and meaning of following parameter bytes. For example, a user press on a remote control will generate a 3-byte frame: a header byte, a <User Control Pressed> opcode (0x44), and an operand byte identifying the button. Including the initial idle time and ...
