SP339BER1-L/TR

SP339BER1-L/TR is an interface for serial port transmission and reception of 15 ns decision time, aiming at serial-port communication interface, designed for low current consumption and stable performance. SP339BER1-L/TR offers an ideal solution for driving and receiving operations. This article will introduce the application fields and working principle of SP339BER1-L/TR.

Application Fields

The SP339BER1-L/TR provides a number of uses in a variety of fields. It can be used in instrument control, medical equipment, bar code scanners, communication devices, printers, servers and other transmission rated applications. It is available in different pin configurations ranging from 2 to 8 and is also available with an integrated ESD protection of up to 8KV. The schottky diode clamping circuit allows the SP339BER1-L/TR to have a low standby current consumption and high signal integrity.

The SP339BER1-L/TR is designed to allow its users to use it when the requirement of serial port transmission and its decision time is less than 15 ns. It has the ability to reduce the power consumption in standby mode and meet the requirements of a variety of data formats. This interface can also automatically switch from transmit to receive mode, making it very suitable for applications with frequent data transmission.

Working Principle

The working principle of SP339BER1-L/TR is relatively simple. It provides an interface to connect two electrical two signal lines such as RS232 or RS422. The signal transmission and reception is done in parallel to ensure smooth data transport. The signal transmitted is received by the transmitter and received by the receiver. The received signal is then processed by the receiving circuitry.

The SP339BER1-L/TR uses a schottky diode clamping circuit to produce a digital signal in response to the input signal. The digital signal is used for digital control signals and for the precision timing required for data transmission and reception.

During reception, the circuit has two active stages: receiver to get the signal and decision circuit to determine the value of the input signal. The receiver is triggered by any voltage change on its pins. It will wait until the signal remains unchanged for a set period of time before it determines that it is in a valid state. The decision circuit compares the received signal to a predetermined threshold. If the received signal is above the threshold, a mark signal is returned. If the received signal is below the threshold, a space signal is returned.

During transmission, the SP339BER1-L/TR driver circuit is responsible for producing the digital signal for the output pin. This digital signal is then converted to a logic level signal by the transmitter. The logic level signal is then transmitted to the device at the other end of the line.

Conclusion

The SP339BER1-L/TR is an interface for the serial port transmission and reception of 15 ns decision time designed for low power consumption and high signal integrity. It is available in different pin configurations and is suitable for a variety of transmission related applications. The working principle of SP339BER1-L/TR is relatively simple and consists of a receiver, decision circuit, and driver circuit.
