MAX220EWE+

The MAX220EWE+ is a high-performance ESD and EMI-protected RS-232/V.24 transceiver that provides a data transfer speed of 20 MBd. It integrates signal attenuators and has a high reliable voltage compliance capability that allows it to work in a changing variable non-linear environment. It is matched to the national lowest RF current standards, providing a 25 dB impedance match and is resistant to disturbances within the low asymmetry and DC power voltage range. In addition, it features the lower zero voltage and higher standard ground current that is necessary for connecting and protecting applications, such as mobile/wireless devices, control and measurement system etc.

The MAX220EWE+ has a Siemens PSS7V power supply. This power supply features an integrated main power, standby power, and power saving control program; it also has a 10-level limiting audio suppression that can effectively suppress both linear voltage and non-linear voltage sent to the receiver by external devices such as drivers, passengers equipment and wireless filters, to protect the system from electromagnetic interference while also helping improve transmission performance.

The working principle of the MAX220EWE+ is to control the signal conversion and synchronization data transfer by means of a component group, components, and circuits. It utilizes an all-digital transceiver that is used for control signals, filters, drivers and receivers circuit structures, to provide optimal EMC/ESD performance and guarantee of high performance data transfer and low power operation. It also utilizes a tuning design to the RS-232/V.24 signal standards to accomplish the lowest zero current and high standard ground current.

In order to guarantee the best ESD/EMI electrical performance, the MAX220EWE+ utilizes a three-level ESD/EMI protection grade design. All ESD/EMI protection frameworks are located before the Radio Frequency Signal in order to effectively suppress high and low frequential electromagnetic interference, the grade of which can reach IEC 61000-4-2,3,5,6/EN61000-4-2/3/5/6. As such, the MAX220EWE+ is an ideal choice for analog and digital systems, providing the best EMC/ESD and RFI/EMI performance.
