Introduction

TFF11101HN/N1X, also known as High Speed, Low Power Time-to-Digital Converter (TDC) is a device used for frequency measurement. It provides high accuracy performance in microsecond resolution, making it suitable for applications where fast data transmission or very fast clock edge detection is needed. Crystals, such as quartz, are used to generate the time determined by the TDC with lower power consumption than traditional frequency measurement methods.

Application Field

TFF11101HN/N1X can be used in applications that require frequency measurement, such as high speed communication systems, frequency control systems and timing systems. It also has applications in medical, automotive, consumer and industrial fields. It is capable of detecting high speed clock edges and making accurate frequency measurements with microsecond resolution.

It can be used to measure and control system clocks in consumer electronics systems such as PCs, smartphones, tablets and gaming systems. Automotive application can use the TFF11101HN/N1X for engine control and monitoring of engine performance. It can also be applied for temperature control applications in industrial machinery and for analysis of heating and cooling systems. In medicine, it can be used to control and monitor patient-specific device used for diagnosis and treatments such as pacemakers or insulin pumps.

Working Principle

The working principle of the TFF11101HN/N1X is based on a time to digital converters that integrates multiple quartz crystal oscillators and incorporates internal circuitry to measure and compare the two frequencies with nanosecond accuracy. The oscillators are triggered by an external clock signal and then the frequency of each oscillator is compared with each other. The difference in the frequency is computed by subtracting each frequency from the other. The difference in the frequency is ultimately converted to a digital signal.

The quartz crystals used in the oscillators are highly stable, making them suitable for applications where accuracy is essential. The quartz crystal also uses low power, which makes it more energy efficient than other traditional frequency measurement methods. For example, the TFF11101HN/N1X has about 75% less power consumption than an Arduino-based frequency detector.

The TFF11101HN/N1X also has other features such as an built-in status monitor, Digital to Analog converter (DAC) for frequency adjustment, a digital interface for controlling the oscillators and an I/O port for connecting to external digital devices. It also has a programmable time delay feature that enables the TDC to start sampling one second after the external clock signal is received. This feature increases the accuracy of the measurement by virtually eliminating the delay between the external clock signal and the TDC sampling process.

Conclusion

TFF11101HN/N1X is a reliable, low power, high speed time to digital converter, capable of making microsecond resolution frequency measurements. It can be used in consumer electronics, automotive, medical, industrial and other applications that require frequency measurement and comparison. Its low power consumption and quartz stability make it ideal for applications where accuracy and reliability are essential. Finally, its programmable time delay feature gives it the unique capability to start sampling one second after the external clock signal is received, and this further increases the accuracy of the measurement.
