DS92LV040ATLQA: Application Field and Working Principle

The DS92LV040ATLQA transceiver is a small, low cost, low-voltage, single-channel transceiver designed to communicate point-to-point on multi-mode multimode, or single-mode Optical Fiber. This transceiver is widely used in applications such as switches, burglar alarms, loudspeakers and microphones, printers, industrial automation, optical communication systems, and security systems. It is also widely used in government and military communications, aerospace, and photonics. This transceiver is widely available from leading electronic component manufacturers.

Performance and Features

The DS92LV040ATLQA transceiver is a full-duplex, low-voltage, single-channel device. It operates in either unidirectional or bidirectional modes. The transceiver features an integrated DC-DC converter that allows the device to operate at a low voltage (1.5V). It also features an adjustable output voltage range of 1.5-5V. This transceiver has an on-chip active differential receiver and transmitter. The active features of the receiver enable enhanced noise rejection, making it ideal for low noise applications. The transceiver also features an evenly-matched termination so that reflection of energy can be reduced. The device is designed to meet optical fiber transmission requirements and is capable of providing accurate data transmission at high speeds.

Working Principle

The amplitude modulation in the transceiver ensures the transmitter output is constant regardless of the logic level of the drive signal. This is done by changing the current induced in the output. The transceiver includes two pins for controlling the receiver’s input threshold and two pins for controlling the differential current. When the drive signal is applied, the receiver\'s differential current is converted into a voltage. This voltage is compared with the threshold and if it matches the required threshold, a logic 0 or 1 is delivered at the receiver’s output depending on the drive signal. The transceiver also includes optional features, like adjustable termination impedance and a programmable speed mode, that provide greater flexibility in the system\'s design.

Conclusion

The DS92LV040ATLQA transceiver is a small, low cost, low-voltage, single-channel transceiver designed to communicate point-to-point on multi-mode multimode, or single-mode Optical Fiber. Its features, such as adjustable output voltage range, active differential receiver and transmitter, adjustable termination impedance and programmable speed mode, make it an ideal device for applications involving low noise, high speed and accuracy. In addition, its low voltage operation and wide range of operational features make it an ideal device for a variety of applications.
