The clock/timing - application specific category identifies products that are designed to provide a precisely timed pulse or signal in order to control the operation of a specific task or process. The 9DBL 411AKLF is an example of clock/timing application specific.

These devices are designed to provide a precise, high-frequency and low jitter clock signal output with tight stability from the single and dual output references. This is achieved through tight component tolerances and careful selection of crystals and discreet components. These devices are designed for use where the utmost accuracy and stability are critical for time and operation-critical applications.

The 9DBL 411AKLF has two independent outputs, one fast output and one slow reference output. Its frequency output range is 10KHz – 1.6 GHz with a typical phase noise of -154 -107 dBc/Hz. It has a wide input voltage range of 1.2 V to 5.5 V and a working temperature range of -20 C - 80 C.

The fast output of the 9DBL 411AKLF provides a very accurate and stable output clock signal even when driven with a dynamic input clock. The dynamic input clock can have an input frequency variation of up to 8 % before it affects the output clock signal. This dynamic range makes the 9DBL 411AKLF ideal for applications where the input frequency is constantly changing and requires an accurate and stable output signal, such as 3G or 4G data modems.

The slow reference output of the reference is a continuous square wave signal with buffered outputs and a wide range of frequency. This slow reference output is ideal for applications requiring a slow reference clock such as RSA encryption and other cryptographic processes. It can also be used to set up a frequency distribution system for multiple processes.

The 9DBL 411AKLF has a number of features designed to reduce noise, such as an integrated negative differential resistance (NDR) circuitry, an optimized on-chip termination scheme and an optimized substrate.¹ These features work together to keep the signal low in noise and interference, resulting in reliable and stable signal transmission.

The main applications for the 9DBL 411AKLF include high performance data communication systems and secure signal distribution systems. It is used in a variety of time- and process critical applications such as those found in data centers, telecom networks and military operations. The 9DBL 411AKLF is also used in high speed local area networks, mobile networks and industrial automation systems.

In conclusion, the 9DBL 411AKLF is a clock/timing - application specific device that provides a highly accurate and stable output clock signal even when driven with a dynamic input clock. Its two independent outputs and advanced noise reduction features make it ideal for a wide range of time- and process critical applications.
