DS21348T is a half-duplex synchronous transceiver with a selectable data rate up to 5 Mbps and a synchronous interface to the host processor. This device is ideal for use in RS-232, EIA-485 and V.35 systems. It supports both synchronous and asynchronous data transmission, as well as a protocol-controlled speed selection. For error-free data transmission, there is a data signal conditioning circuit that helps eliminate ringing and other interferences.

Application Field

The DS21348T can be used in various types of data communications systems that require reliable transmission of data over limited distances. It is used in applications such as industrial automation, automated manufacturing or robotics, medical or automotive systems as well as point-to-point connections in office and telecommunications networks.

The DS21348T is also suitable for applications such as data collection systems in remote locations, embedded controllers, instrumentation systems, and data communications in environmental monitoring or data logging systems. It can be used for SCADA or for multiple protocols such as Modbus, Profibus and CAN.

Working Principle

The DS21348T is a synchronous transceiver that uses an advanced data signal conditioning circuit to ensure error-free data communications. It features a reduced-voltage level CMOS driver which eliminates ringing and interference, resulting in more reliable data communication.

The DS21348T can be operated in either asynchronous or synchronous mode and supports both single-wire and differential signaling. In asynchronous mode, it can be set up to send data with pre-determined parameters of word length and stop bits. The synchronous mode supports auto-bauding, serial protocol auto-negotiation and handshaking.

In addition, the DS21348T provides advanced error checking, including CRC and parity, to ensure data reliability. It also incorporates programmable power management, allowing for low power operation in idle modes. The device also comes with a low-cost option for supporting format F/X34 for external line regulation.

The DS21348T is an ideal solution for a wide range of data communications applications. It can be used in a variety of settings, including industrial automation and embedded control systems, instrumentation systems, and data communications networks. Its advanced data signal conditioning makes it an ideal solution for error-free data communication over limited distances.
