The IDTCV115-2PVG8 is a high-performance programmable interval timer, designed for timing applications. It can be used in either a clock/timing or application-specific programmatic setting. This article will provide an overview of the IDTCV115-2PVG8’s application field and working principle.

The IDTCV115-2PVG8 is a programmable digital timer with a 12-bit up counter. It is tailored for general-purpose timing and control applications requiring high resolution and accuracy. Comparing to its predecessor, the IDTCV115-1PVG8, the IDTCV115-2PVG8 offers more flexibility in setting the timing resolutions and accuracy, which makes it suitable for a wide range of applications such as, real-time clock synchronization, real-time scheduling, and cyclic process control. Moreover, it can provide multiple outputs with different timing accuracy. The required time interval and accuracy can be programmatically set through its internal registers.

The IDTCV115-2PVG8’s working principle is based on a ‘free-running’ 12-bit counter. When the counter is started, it starts counting up from 0 in synchrony with the clock cycle. After a certain number of counts, the counter generates an output signal, depending on the pre-programmed start and end count/timing values. The output signal can be used to start or stop a process or to trigger some other in-system event.

The IDTCV115-2PVG8 provides an adjustable resolution, ranging from 0.125 microseconds (1µs) to 10 milliseconds (10ms). The 10ms resolution results in a maximum output rate of 100Hz, while the 0.125µs resolution gives an optimal output rate of up to 8kHz. Notably, the resolution adjustment can be done via a register within the timer’s internal memory, which significantly increases its flexibility and makes it suitable for a wider range of applications. In addition, the user can decide either to generate output signals every given interval or to generate a single output at the end of the programmed timing cycle.

The IDTCV115-2PVG8 also offers the option for setting the number of output signals to be generated. This flexibility allows for individual output timing accuracy and can be used for setting up variable pulse-widths and frequency modulated signals. Additionally, it features two independent latchable output channels, each of which can be used for a different timing cycle.

In conclusion, the IDTCV115-2PVG8 is an advanced programmable timer, designed for timing applications. It offers adjustable resolution and accuracy and provides multiple output signals from one chip. The timer is designed for use in both a clock/timing and application-specific set up, allowing for flexible and accurate timing for a variety of processes and events.
