The IDT2305B-1DCI8 is a programmable clock generator and part of the family of clocks and timing solutions from Integrated Device Technology. This versatile product generates output frequencies up to 200MHz, and allows for adjustments as small as 100ppm over a variety of different temperature ranges. These features make the IDT2305B-1DCI8 a perfect choice to meet a wide variety of timing applications, giving users the flexibility to customize their design.

The IDT2305B-1DCI8 can be used in applications such as servers, storage, networking and communications hardware where accurate timing is essential. It is well-suited to provide frequency and clock output for server based systems, as well as for end-user products like mobile phones, tablets, medical devices and more. With its low jitter and low phase noise characteristics, the IDT2305B-1DCI8 offers excellent accuracy in a wide range of temperatures. Additionally, it is also well-suited to support higher-speed interfaces such as USB 3.1, Fiber Channel and SATA.

The working principle of the IDT2305B-1DCI8 begins with a crystal oscillator block. This block uses an internally generated reference clock to generate an output frequency. The output frequency can be adjusted in small increments using a serial bus. The generated frequency is then sent to a loop filter circuit which adjusts the magnitude and phase of the frequency and then sends it to a phase detector circuit. This phase detector compares the phase of the output and reference clocks and adjusts the oscillator voltage to keep the phase difference at zero. The phase adjusted output is then sent to the VCO which amplifies and then sends the signal through an internal isolation channel to the output pins, ensuring accuracy and low power consumption.

The integrated technology within the IDT2305B-1DCI8 makes it an ideal solution for customers needing to create high speed, low power frequency generation. The ability to adjust frequency in such small increments and over a wide range of temperature gives users maximum flexibility. With its good accuracy, low power consumption and excellent EMI performance, the IDT2305B-1DCI8 is an ideal choice for clock generator and frequency synthesis applications.
