Interface - Drivers, Receivers, Transceivers

The TM266DVA1 is a Super High-Speed, Low-EMI, +1.6V I/O, LVTTL Transmitter, Receiver and Transceiver from Texas Instruments. It has been developed specifically to provide low-power, fast data speed, and highly efficient EMI suppression performance into the smallest package size. Designed to function in high-speed data communications, the TM266DVA1 is capable of 1-bit/3-bit maximum transmission performance in full duplex mode.

Application FieldWithin high-speed, data communications circuit applications, TM266DVA1 operates as a Driver, Receiver or Transceiver. It enables data transmission to occur over a long distance, with minimum loss in speed or accuracy. It features integrated ESD protection on its I/O pins, allowing it to be connected directly to sensitive devices, such as personal computers, cellular phones and handheld devices, without the addition of a protective circuit.

Working PrincipleThe TM266DVA1 works by transmitting and receiving digital signals in the form of voltage and current. The transmitter and receiver circuits are built into the same device, allowing it to send and receive data simultaneously. The device contains two input pins, one for transmitting information and one for receiving data.When transmitting data, the low-voltage differential signal (LVDS) protocol is used. The transmitter converts the digital signal into a type of LVDS coding (also known as differential pseudoternary coding or PECL-modulated LVDS). It then transmits the signal to the receiver over an I/O interface, such as a coaxial cable or fiber optics.When receiving data, the receiver converts the received LVDS signal back into its original digital form, before sending it to the intended device. During the data transmission process, the TM266DVA1 can reduce the amount of noise by suppressing electrical interference (EMI) through its built-in EMI shield.In addition to its low-power, high-speed data transmission capabilities, the device also features an isolated power-supply operation mode. This mode is designed to reduce the device’s power consumption and improve its reliability.ConclusionThe TM266DVA1 is a highly efficient, low-power transmitter, receiver and transceiver. It can enable high-speed, low-EMI data transmission over long distances. It is designed for applications such as cellular phones, personal computers and handheld devices, where protection is essential. The device’s integrated ESD protection and isolated power supply mode allow it to function reliably in highly sensitive environments.
