What is the principle of line driver?
The key to the excellent performance of modern communication transmission is the digital modulation and demodulation technology based on high-speed digital signal processing technology. However, in order to send the modulated signal to the twisted pair without distortion and meet the required output power, a high-performance analog interface circuit is needed. The analog interface circuit mainly consists of a line driver circuit, a line receiver circuit, and a hybrid circuit.
Basic Principles
Here, we briefly introduce the requirements of ADSL for line driver amplifier circuits and practical circuits for line driver circuits.
The ADSL specification uses discrete multi tone modulation technology. When the phase of the modulated signals on each subcarrier frequency is consistent, the signal peaks appear. To avoid clipping distortion, the line driver amplifier needs to have a large distortion free dynamic range. The ratio of the peak to effective level of a signal is called the peak to average ratio or “peak factor”, and the peak factor of DMT signals in ADSL systems is 5.3. The following table summarizes the characteristic parameters and electrical requirements of ADSL systems.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 5X00583G01 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
