In this configuration, the display shows hertz directly. When pin 11 of the ICM7027 A is connected to V00, the gating time is set to 0.1 seconds, allowing the display to represent tens of hertz as the least significant digit. For shorter gating times, an ICM7207 can be utilized with a 6.5536-MHz crystal, resulting in a 0.01-second gating when pin 11 is connected to V00, and a 0.1-second gating when pin 11 is left open.
The ICM7027 A and ICM7207 are integrated circuits designed for frequency measurement. The ICM7027 A is capable of displaying frequency values in hertz directly on a connected display. The configuration specifies that connecting pin 11 of the ICM7027 A to V00 sets the gating time to 0.1 seconds. This means that the device samples the input frequency for a duration of 0.1 seconds, providing a stable reading that can accurately represent frequencies in the tens of hertz range as the least significant digit on the display.
For applications requiring shorter measurement intervals, the ICM7207 serves as an alternative. When paired with a 6.5536-MHz crystal, the ICM7207 can achieve a gating time of 0.01 seconds when pin 11 is connected to V00. This allows for more precise frequency measurements, particularly at higher frequencies, as the device can capture more cycles of the input signal within a shorter timeframe. If pin 11 is left open, the ICM7207 defaults to a 0.1-second gating time, similar to the ICM7027 A configuration, providing flexibility depending on the measurement needs.
In practical applications, these configurations can be utilized in various electronic devices requiring frequency measurement, such as signal generators, oscilloscopes, or frequency counters. The choice between the ICM7027 A and ICM7207 will depend on the specific requirements of the application, including the desired measurement precision and the frequency range of interest.In this configuration, the display reads hertz directly. With pin 11 of the ICM7027 A connected to V00, the gating time will be 0.1 second; this will display tens of hertz as the least significant digit. For shorter gating times, an ICM7207 can be used with a 6.5536-MHz crystal, giving a 0.01 second gating with pin 11 connected to V00, and a 0.1 second gating with pin 11 open. 🔗 External reference
