Disadvantages: - Requires LVDS-compatible devices for proper operation - Limited to a maximum data rate of 400 Mbps

Working Principles

The SN65LVDS049PWG4 operates by converting parallel data inputs into a serialized data stream using LVDS technology. The parallel data is received through the D0-D3 inputs and synchronized with the CLK input. The serializer then converts the parallel data into a high-speed serial data stream, which is available at the Y0-Y7 outputs.

For serial-to-parallel conversion, the SN65LVDS049PWG4 receives a serial data stream at the Y0-Y7 inputs and synchronizes it with the CLK input. The deserializer then converts the serial data back into parallel data, which is available at the D0-D3 outputs.

Detailed Application Field Plans

The SN65LVDS049PWG4 finds applications in various fields, including:

1. Automotive: Used in automotive infotainment systems, where high-speed data transmission is required between different components.
2. Industrial Automation: Enables efficient communication between industrial control systems, sensors, and actuators over long distances.
