The application field and working principle of TFF1024HN/N1,115 is mainly used in the clock/timing sector, namely application specific. It is a frequency divider chip, which is used to divide the input clock frequency, reducing the frequency to the desired output rate. It is designed primarily for high-accuracy, low-jitter frequency distributions systems.

The TFF1024HN/N1,115 divides an input clock by some fixed or programmable value, typically an integer or fractional multiple. It is a complete, ultra low power frequency divider with an operating temperature range of -40 to +85°C, allows precision adjustment of frequencies, and can be used to divide frequencies up to 500 MHz into divisions ranging from ½MHz to 500MHz. Its output frequency is determined by a selectable frequency divisor that consists of two fields. The ‘T’ field consists of two bits and determines the type of the most significant bit of the second field, the ‘N’ field. The ‘N’ field consists of 8-bits, and the ‘T’ field controls which bit is the most significant bit in ‘N’, which in turn determines the range of the output frequency of the frequency divider.

The TFF1024HN/N1,115 is ideal for use in a variety of applications such as constructing frequency multipliers and dividers, frequency counters, center-frequency selectors, or injection-locked or low-jitter oscillator configurations. It is particularly well suited for network clocks, backplanes, instrumentation and communications systems that require low-jitter frequency dividers. Its relatively short propagation delay time and low power consumption make it suitable for many applications involving low-jitter clock distribution, such as delay-locked loops and clock/data recovery applications.

The TFF1024HN/N1,115 comes in a variety of packages including TSOP-5, TSSOP-8, TQFP-20, and LGA-52 for low-cost implementation, and can be programmed in standard microprocessor interfaces such as 1-wire, I2C, and SPI bus. It has many desirable features, such as low jitter, low power consumption, and small size. The TFF1024HN/N1,115 is the ideal solution for all clocking and timing applications that require precision frequency adjustment, while delivering cost and power efficiency.
