SSP721A
SSP721A is a single chip transceiver developed for Meter-Bus standard (EN1434-3、EN13757) applications.
The SSP721A interface circuit adjusts the different potentials between a slave system and the Meter-Bus master. The connection to the bus is polarity independent and supports full galvanic slave isolation with optocouplers. The circuit is supplied by the master via the bus. Therefore, this circuit offers no additional load for the slave battery. A power-fail function is integrated. The receiver has dynamic level recognition, and the transmitter has a programmable current sink. A 3.3V voltage regulator, with power reserve for a delayed switch off at bus fault, is integrated.
SSP1922
SSP1922 is a high accurate time measurement (TDC) circuit. SSP1922 integrates analog comparator, analog switch, Schmidt flip-flop and other internal devices, thus greatly simplifying the peripheral circuit. At the same time, the first wave detection function is added inside, so that the anti-interference ability is greatly improved. The programmable offset range of the comparator is increased to ±35mV, the sampling accuracy can be improved.Measuring the relative pulse width of the first wave gives the user an indication of the strength of the received signal. Through this hint, we can judge the abnormal detection of ultrasonic transducer, the increase of wall covering, the presence of bubbles in water and so on. The Start-TOF-Restart command can complete a measurement of ultrasonic time difference (upstream and downstream) and data reading, so as to greatly reduce the software operation and power consumption. Compatible with TDC – GP22.
