The MAX3227CAE+ is an advanced 5 Mbps and 1 Mbps triple RS-232/HS-232 line transceiver from Maxim Integrated Products. It allows for compatible serial communication between DTEs (data terminal equipment) such as a PC and DCEs (data communication equipment) such as modems. This asynchronous line transceiver features high data rates, low power consumption and an integrated low voltage differential signaling (LVDS) interface.The MAX3227CAE+ is ideal for high-speed serial signaling applications requiring low power consumption and small footprint.

Applications

The MAX3227CAE+ is optimal for applications requiring low-power, high-speed data transmission, such as:

• Portable computing, such as notebooks, PDAs, and smart phones
• GPS nodes, medical equipment, and other handheld instrumentation
• Telecommunications, industrial, and utility devices
• M2M (Machine-to-Machine) communication

Features

The MAX3227CAE+ has a number of features which make it a valuable choice for modern systems, such as:

• High-Speed 5 Mbps and 1 MPH Operation
• Integrated LVDS Interface
• 3-Volt Supply with Low-Power Engineering Mode
• Eliminates Data Retransmission Reduces Power Requirements
• Low-cost solution provides the highest level of performance available
• Advanced design provides superior data integrity

Working Principle

The MAX3227CAE+ line transceiver is a low power, high speed, triple line RS-232/HS-232 transceiver. It enables transfer of 12-bit words of data at data rates up to 5 Mbps between devices. It converts the logic-level signals present at the driver outputs to balanced line signals for transmission over asynchronous communication lines, and vice versa.The LVTTL (Low Voltage Transistor Transistor Logic) signals from a DTE (Data Terminal Equipment) are converted to equivalent balanced line signals for transmission over the compatible asynchronous communication line. The MAX3227CAE+ transceiver converts the line voltage on the communication line to equivalent logic levels.

The logic outputs are also used to control line current via the current-limited drivers. It contains an in-line driver and an in-line receiver. Each of the triple line transceivers has a 3V supply. The logic outputs are open drain, providing not only pull-down capability but enabling both the positive and negative polarities of the driven signal. The lines are short-circuit protected. The MAX3227CAE+ provides a higher system integrity than other transceivers and is capable of producing signals over 10x faster than competing products.

Conclusion

The MAX3227CAE+ is an advanced 5 Mbps and 1 Mbps triple RS-232/HS-232 line transceiver from Maxim Integrated Products. It integrates LVDS interface and a 3V supply with low-power engineering mode, eliminating the need for data retransmission and reducing power requirements. It has a number of features which make it a valuable choice for modern systems and applications requiring low-power, high-speed data transmission. The MAX3227CAE+ transceiver is a low power, high speed, triple line RS-232/HS-232 transceiver. It enables transfer of 12-bit words of data at data rates up to 5 Mbps between devices and is capable of producing signals over 10x faster than competing products.
