It offers many unique features and performance, such as a true 16 frequency divider, independent internal locking circuits for the low-frequency and high frequency programmable outputs, and ultra-low jitter of less than 1ps rms.

Application Fields

The LTC6991IS6#TRPBF is particularly well suited for use in the following application fields:

Industrial and Consumer Electronics

The LTC6991IS6#TRPBF is well suited for use in industrial and consumer electronics thanks to its wide input voltage and output drive capabilities. Its high accuracy and precision outputs can help alleviate any timing issues that normally plague these applications.

Precision Electronics

The LTC6991IS6#TRPBF is also particularly well suited for precision electronic applications which require tight timing specifications. Its output accuracy of 0.01ppm ensures that the system maintains a steady, reliable clock, while its low jitter of less than 1ps rms helps prevent errors and incorrect readings.

Clocking Applications

The LTC6991IS6#TRPBF is also ideal for clocking applications due to its wide input voltage range and high output accuracy. Its true 16 frequency divider allows for precise synchronization and control of the system’s clock, while its high output drive amplitude of up to 3V ensures consistency and reliability.

Working Principle

The LTC6991IS6#TRPBF utilizes a 16-bit frequency divider along with a dual lock-in circuit to generate a precision low-frequency and high-frequency output. It also uses a tested 4-bit temperature compensation circuit that allows the device to maintain a constant output frequency and drive amplitude over temperature. The frequency divider is used to divide the input clock signal by a programmed 16-bit value. The input reference clock and the frequency divider output are both locked to the accurate, low-noise reference oscillator. The frequency divider is then used to generate the low-frequency and high-frequency outputs. The dual lock-in circuit is used to maintain both the low-frequency and high-frequency output in the desired frequency range. The lock-in circuit is a combination of a voltage-controlled oscillator (VCO) and an RF envelope detector, which together control the VCO frequency. The lock-in circuit ensures that the device stays within the desired frequency range and remains accurate over normal operating temperature ranges.

Conclusion

The LTC6991IS6#TRPBF is an excellent choice for applications requiring a precise and reliable programmable timer and oscillator. It features a true 16 frequency divider, independent internal locking circuits for the low-frequency and high frequency programmable outputs, output accuracy at 0.01ppm, output drive amplitude of up to 3V, and a wide input voltage range (1.8V to 5.5V). It is especially suitable for industrial and consumer electronics, precision electronics, and clocking applications.
