In electronic engineering, the SN65LVDS100DRG4 is an integrated circuit (IC) for operating as a low-voltage differential signaling (LVDS) line driver. It is a single-channel device, integrating a transmit line driver with the ability to detect incoming logic states from the receiver. It outputs a differential signal in response to TTL (transistor–transistor logic). The device is designed to expand the reach of standard logic signals beyond a few feet and to reduce the amount of jitter typically found with single-ended logic signals in noisy environments. It also offers increased noise immunity.

The SN65LVDS100DRG4 is part of Texas Instruments’ family of interface ICs, and it is designated as a "Signal Buffers, Repeaters, Splitters" product. As its name implies, it is a signal buffer that is meant to drive, convert, and buffer a signal by outputting a differential signal in response to TTL input. The following section will discuss this device’s applications and working principles.

Applications

The SN65LVDS100DRG4 is targeted at applications requiring low-voltage differential signaling, such as LCD panels and displays, digital video, and audio applications. It works well with the SN65LVDS950, which is an analog multiplexer/demultiplexer (MUX/DEMUX) for switching analog signals. Both these devices are suitable for applications requiring high-speed data transfer, like parallel DVI and LVDS displays.

The SN65LVDS100DRG4 provides high accuracy, low-noise signal transmission, and data transmission speeds up to 1 Gbps over long distances. It has low power consumption (1.8 mW/channel) and can be used in hot-plugging applications – that is, in applications where devices may be disconnected when powered up. Additionally, the driver is compatible with many LVDS-compatible solutions, and its integrated differential inputs increase its noise immunity, making it ideal for noisy environments.

Working Principle

The SN65LVDS100DRG4 is a simplified version of the digital transmitter/receiver devices used in data communication systems. It consists of two major parts: the transmitter and the receiver. The transmitter encodes the digital input (TTL logic levels) into a differential analog signal while the receiver decodes the differential signal back into a TTL logic level.

The transmitter part of the device is composed of two NMOS transistors – one as the driver, and one as the receiver – connected in series. The two NMOS transistors form the differential amplifier, and perform the voltage level shifting of the digital input for transmission. When the input is high, the top transistor conducts and pulls the output high, and similarly, when the input is low, the bottom transistor conducts and pulls the output low. The transmit line operates from a supply voltage of 1.65 V to 3.0 V, and the output can be set to any voltage between 0.4 V and 1.4 V.

The receiver part of the device is composed of two differential amplifiers connected in cascade. The first differential amplifier is composed of two complementary NMOS transistors, and acts as a comparator. The second differential amplifier is composed of two NMOS transistors and acts as a logic-level shifter. The receiver is designed to detect differential signals of 0.2 V to 1.2 V, allowing the device to receive both uni-polar and bi-polar signals.

The SN65LVDS100DRG4 is a highly versatile device, offering a number of useful features in data communication applications. From long distance digital transmission over short distances, to low power consumption, to high noise immunity, this device is perfect for any LVDS-compatible project.
