DS14C232TMX

Interface - Drivers, Receivers, Transceivers

DS14C232TMX is a standard dual transceiver used in many electronics applications. It is designed to interface two biphase communication channels such as two RS-422/RS-485 differential pairs, LVDS, TMDS, and CML digital signals. The transceiver features an integrated internal level shifter between an LVTTL/CMOS 5V logic bus and a differential bus, which is compliant with a wide range of voltage levels. The transceiver supports fast switching speeds up to 25 MBaud and has a low power consumption of just 2.8 mW per channel.

Application Fields

The main application fields for the DS14C232TMX transceiver are communications and networking. It is used to interface two channels for data transmission and reception. It is commonly used in:

• Networking applications
• High speed serial buses
• Industrial automation process control
• Multi-point communication systems
• Automotive data communication

Working Principle

The DS14C232TMX transceiver features an integrated internal Level Shifter between a differential bus (LVDS, TMDS, or CML) and an LVTTL/CMOS 5V logic bus. The Level Shifter allows the transmission and reception of data between the two types of buses with a bidirectional exchange of the data.

The data rate is determined by the bus and the data format, which is determined by the Level Shifter. The Level Shifter ensures that the data is transmitted in the desired format by translating the data from the LVTTL/CMOS 5V logic bus to the proper voltage level for the differential bus.

The Level Shifter also ensures that the data is transmitted at the desired data rate. The data rate is determined by the clock speed, which is held in a divisor register. The divisor register is adjustable to allow the data rate to be adjusted based on the desired application.

The DS14C232TMX also features a power supply rejection rate of up to 70dB, which makes it suitable for use in a wide range of power distribution systems. It supports a wide range of operating temperature range from -40°C to +85°C.

Conclusion

The DS14C232TMX is a versatile dual transceiver designed for use in a wide range of communications and networking applications. It features an integrated internal Level Shifter between an LVTTL/CMOS 5V logic bus and a differential bus and is compliant with a wide range of voltage levels with Fast switching speeds up to 25 MBaud and a low power consumption of just 2.8 mW per channel.
