DS21T07E+

Interface - Signal Terminators

Interface-signal terminators are commonly used to provide necessary protection for sensitive circuits by limiting any transient voltage signals within a system. The DS21T07E+ is a new type of such terminator that differs from conventional terminators in its straightforward design, high-efficiency performance, and cost effectiveness.

Application Field

The DS21T07E+ terminator is designed for optical fiber communication systems. By providing a terminating impedance, it ensures stable and reliable communication between the fiber optic transmitter and receiver without affecting any of the signals involved in the loop. This terminator is suitable for use in LAN networks, DSL and FTTP systems, as well as active device termination, thereby simplifying the installation process.

The DS21T07E+ enables the transmission of high-speed differential signaling, wide bandwidth applications, and single-ended driven applications as well. It features a fast edge rate and excellent signal fidelity, which allows the signals to actualize their maximum operating bandwidth.

Working Principle

The DS21T07E+ terminator consists of a dielectric band-pass filter and series-parallel networks of resistance and capacitance, which help achieve controlled termination capabilities. The network of resistors, capacitors, and inductors allows the passage of all frequencies, including higher frequency signals, up to a certain threshold. The filter capacitors installed in the terminator eliminate most of the high-frequency noise and distortion, which ensures stability of communication.

The alternation of the inductance across the transmitter and the differential impedance limits the amplitude of the voltage, thus controlling both the rise time of the signal and attenuation of the output. This helps reduce the total harmonic distortion and eliminate the potential of any unwanted voltage transient signals.

Conclusion

The DS21T07E+ is an extremely reliable, efficient and cost-effective interface-signal terminator. By providing effective termination, it helps ensure the stability and efficiency of any communication system connected. In addition, it is capable of handling both narrowed and wide bandwidths, thus optimizing the performance of transmission signals.
