The SN65LVDS32DRG4 is a feature-rich LVDS bus transceiver introduced by Texas Instruments. This device performs as a driver and receiver that supports various data rates and protocols, such as PCI Express, Ethernet, High-Speed Serial Interfaces, and more. It is designed to support the increasing demand for higher bandwidth that today’s systems applications require. It is ideal for use in applications such as digital still and video cameras, medical imaging, and test and measurement equipment.

LVDS (Low-Voltage Differential Signaling) utilizes differential signaling for fast data transmission over short distances. It offers numerous advantages versus conventional logic-level transmissions, including lower power consumption, smaller package sizes, and higher noise immunity. The SN65LVDS32DRG4 is designed to operate at data rates up to 400 Mbps and offer reliable and efficient data transfer.

The SN65LVDS32DRG4 is available in two 14-pin TSSOP packages, each featuring a dual-channel LVDS interface and two SMA connectors. It includes an integrated clock receiver, separating it from the data receiver and driver. The clock receiver is configurable via an onboard resistor, allowing users to select a suitable frequency. It also features an enable/disable pin, allowing it to be easily disabled in applications where LVDS connectivity is not needed.

The SN65LVDS32DRG4 is designed to meet the stringent requirements of industrial, medical, and automotive applications. It features an input voltage range of 3.3V to 5.25V, allowing for operation in a wide range of systems. It is specified for operation from -40°C to +85°C and has an Existing Image Radiation Immunity assurance rating of 10kV.

The SN65LVDS32DRG4 uses voltage mode LVDS logic, with the driver and receiver separated from one another. The driver consists of a differential gain stage, along with two unity gain output stages. The receiver portion is a differential impedance-matched input, with a power-down logic. It includes a rear termination resistor that allows for customization to optimize performance.

At the heart of the SN65LVDS32DRG4 is the integrated 5V DC-to-DC converter, which allows the device to operate at 5V while the logic voltage remains at 3.3V. The converter includes two on-chip charge pumps and a voltage regulator and provides very low power consumption. The device also features an in-rush current limiter, to protect the on-chip components from the system’s power supply transient.

To ensure reliable data transmission, the device is designed with a number of safeguards, such as an overtemperature warning and thermal shutdown protection. It also includes a voltage and current monitoring system to detect any faults in the device or the system. In addition, the SN65LVDS32DRG4 offers an adjustable slew rate feature and an output disable function to reduce signal distortion and enhance system performance.

The SN65LVDS32DRG4 is an ideal solution for applications that require low-power, reliable, and efficient LVDS interface communication. It is the perfect choice for applications that require the highest performance, such as in digital still and video cameras, medical imaging, and test and measurement equipment.
