| Package | QFN-32(5x5) | Model Number | MSK1022 |
The MSK1022 is a high-precision time measurement circuit that integrates analog comparators, analog switches, and Schmitt triggers to simplify external circuitry. It features a first echo detection function for enhanced anti-interference capabilities. By reading the relative width of the first echo pulse, users can receive a signal strength indication, which helps identify anomalies such as abnormal ultrasonic transducers, increased wall coverings, or air bubbles in water. The device allows for ultrasonic time-of-flight (TOF) measurements (downstream and upstream) and data reading via commands, reducing software operation and power consumption.
| Feature | Details |
| Core Functionality | High-precision time measurement circuit with integrated analog comparator, analog switch, Schmitt trigger. First echo detection for improved anti-interference. |
| Measurement Capabilities | Ultrasonic time-of-flight (TOF) measurements (downstream and upstream). Reading of first echo pulse width for signal strength indication. |
| Measurement Range 1 | Dual-channel single-precision mode: 90ps Single-channel dual-precision mode: 45ps Measurement range: 3.5ns (0ns) to 2.4s Minimum pulse interval: 20ns, up to 4 pulses receivable. |
| Measurement Range 2 | Single-channel single-precision mode: 90ps Dual-precision mode: 45ps Quad-precision mode: 22.5ps Measurement range: 500ns to 4ms (at 4M high-speed clock) Up to 3 pulses measurable, with automatic data processing. |
| Analog Input Circuit | Integrated analog switch for input selection. Integrated Schmitt trigger. |
