Modern day electrical systems are becoming more complex, as engineers strive to create more specialized designs that require sophisticated timing and control features. The need for a product that can provide the necessary accuracy, flexibility and precision in clock and timer applications is critical in these today’s modernized systems. The LTC6995IS6-2#TRPBF is a popular choice among engineers who seek a reliable and highly accurate clock/timer device. The device offers many features that make it an ideal solution for a wide range of time and timer applications.

Description

The LTC6995IS6-2#TRPBF is a programmable clock/timer oscillator device with an automatic tuning feature. It also has a programmable divider, providing adjustable frequency division from 1 to any desirable value. The device can operate in two modes, frequency hopping mode or multiple frequency division mode. In frequency division mode, the number of divisions is determined by the application, while in frequency hopping mode, the device can change frequency division ratios quickly and accurately according to external signals.

The frequency division range is 0.25Hz to 25kHz, with a maximum division rate of 200kHz. Frequency division accuracy is ± 0.1%, and the frequency division stability is ± 0.05%. An adjustable frequency division range of 0.5kHz to 32kHz is available when the device is set to frequency hopping mode.

The terminal count range is 8-bit, allowing for a maximum of 256 divisions, and the pulse count range is 10-bit, allowing for a maximum of 1024 divisions. The LTC6995IS6-2#TRPBF also has two programmable outputs, which can be configured for single or dual output operation. One of the outputs has a programmable duty cycle.

Applications

The LTC6995IS6-2#TRPBF is suitable for a wide range of time and timer applications, including mobile phones, personal digital assistants (PDAs), digital television receivers, power supply control circuits and display devices. Its programmable divider and adjustable frequency division range make it ideal for frequency hopping applications, such as frequency shifting, frequency hopping spread spectrum (FHSS) and multiple frequency division applications. It is also suitable for use in automotive electronics and medical devices.

Working Principle

The LTC6995IS6-2#TRPBF can operate in both frequency division mode and frequency hopping mode. In frequency division mode, the frequency division range is from 0.25Hz to 25kHz, and the device is programmed to divide the main clock frequency by the number of divisions desired. In frequency hopping mode, the device is programmed to jump between two frequencies as a response to external signals.

For example, when the LTC6995IS6-2#TRPBF is used in a mobile phone application, the device can be programmed to jump between the base band frequency and the carrier frequency in order to extend the battery life of the phone. Similarly, in a medical device, the device can be programmed to jump between two different frequencies to ensure accurate readings. In both cases, the device is programmed to respond to external signals and can adjust the frequency division ratio quickly and accurately.

Conclusion

The LTC6995IS6-2#TRPBF is a versatile and reliable programmable clock/timer oscillator device that can be used in a wide range of time and timer applications. It provides engineers with an accurate and precise clock/timer device that is highly flexible and can be programmed to perform various frequency division tasks. With its programmable divider, adjustable frequency division range and two programmable outputs, the LTC6995IS6-2#TRPBF is an ideal choice for a wide range of time and timer applications.
