Programmable oscillators are used to control frequency, waveform and other characteristics of clock signals. The SIT9005ACE2D-28NB is a state-of-the-art programmable oscillator designed for a wide range of applications. It provides a wide frequency range of 1 kHz to 48 MHz, allowing a user to produce high precision clock signals. Furthermore, the device is capable of supporting multiple spread spectrum waves for EMI reduction.

The SIT9005ACE2D-28NB is ideal for high-end consumer application, communications, and industrial control systems due to its integration of two distinct protocols: SPI and I2C. This allows for external programming of the oscillator’s frequency and other parameters. The device also incorporates several other features, such as a programmable pullability of up to ±200ppm, a low jitter of 5ps (typical), an enable/disable control signal as well as a dedicated reset terminal.

Working Principle

The SIT9005ACE2D-28NB utilizes a Voltage Controlled Oscillator (VCO) based system to produce the desired clock signal. The device contains an internal frequency divider, which divides the output frequency of the VCO by factors of up to 128. A user can program the device with their desired frequency by accessing the SPI or I2C ports. The frequency divider then divides this frequency to create the output signal. Furthermore, the device is also designed with an advanced digital lock algorithm which enables it to bridge any changes in input frequency or temperature with precision.

Applications

The SIT9005ACE2D-28NB offers a wide range of applications due to its versatile nature. It can be used in consumer electronic devices for analyzing, controlling and monitoring various functions. Additionally, it can also be used in communications systems such as GSM, GPRS, CDMA, LTE and others. Further applications include industrial control and datacom, optical network, In-vehicle systems, consumer and industrial networking, set top box and STB applications.

The SIT9005ACE2D-28NB is a cost-effective solutions for a wide range of applications due to its unmatched programming flexibility and low power consumption, making it an ideal choice of programmable oscillators
