The SIT9002AI-23H25Dt programmable oscillator is an ultra miniature 2.5V programmable oscillator, suitable for applications requiring speed and flexibility like PCI Express, USB, SATA, SAS, DVD, and Serial ATA. It has a frequency range of 1.5MHz to 133.3MHz, and a supply voltage of 2.5V ± 0.45V. The SIT9002AI-23H25DT is a highly integrated product that combines the functionality of multiple components in a single, low profile package.

The working principle of the SIT9002AI-23H25Dt programmable oscillator is based on a voltage controlled frequency synthesizer. It consists of two clock outputs, two reference inputs and two programmable registers. The two clock outputs are referred to as Clock A and Clock B. Clock A is used as the system clock, while Clock B is the reference clock. The two reference inputs are for sending and receiving reference signals from the system. These signals are used to set the frequency of the output signals.

The two programmable registers contain data that is used to set the frequency of each output signal. This data is stored in the form of a 16-bit word. The 16-bit word contains a 10-bit word that specifies the reference frequency, and a 6-bit word that contains the 21st harmonic of the reference frequency.

The first eight bits control the reference frequency, and the next eight bits are used to control the 21st harmonic of the reference frequency. The reference frequency is divided by the 21st harmonic and the result is then used to set the output frequency. The 21st harmonic is also used to set the rate of the frequency synthesis process, enabling it to be adjusted to the desired frequency.

The SIT9002AI-23H25Dt programmable oscillator is used in a variety of applications, such as signal transmission in portable communication devices, networking, signal transmission for digital video and audio, as well as in hard disk drive controllers. It can also be used in embedded control systems, automotive systems, gaming systems, and computer peripherals. It is also suitable for use in LTE and GSM applications.

The SIT9002AI-23H25Dt programmable oscillator is an ideal solution for applications requiring a wide range of frequency, speed, and flexibility. It is highly integrated, programmable and cost-effective, making it an excellent choice for any application that requires an ultra-miniature oscillator. The high reliability and excellent performance of this oscillator make it one of the most popular choices in the market.
