Application fields

The SIT9005ACA2D-28SP is designed for a wide range of consumer applications, such as PCs, automotive systems, security systems, mobile phones, printers, and other consumer audio and video systems. Its programmable PLL and DRO architecture makes it suitable for automotive, security and consumer applications, as well as industrial applications where frequency stability is a critical requirement.

Working Principle

The core of the SIT9005ACA2D-28SP is an analog Programmable Oscillator (PLL) which is made up of a Voltage Controlled Oscillator (VCO) and an array of programmable dividers and mixers. The VCO produces a signal at its own frequency, while the dividers and mixers can be programmed to turn the signal frequency into one or more outputs.The dividers and mixers are set up to follow the algorithm of “divide-by-N” and “mix-frequencies”. This algorithm is then used to produce a frequency output at the desired value and a variable phase angle. The frequency output is then locked onto a reference signal, and the phase angle is automatically adjusted so that the PLL can be synchronized with the reference signal.

Conclusion

The SIT9005ACA2D-28SP is a programmable oscillator with a wide range of applications, from consumer electronics to automotive and industrial systems. It features an ultra-low power consumption, making it an ideal choice for mobile device applications. It also supports Max/Min DRO output, voltage-controlled oscillator (VCO) noise specifications, and frequency-locking operation. All these features make this integrated circuit an attractive choice for a wide range of applications, including digital TV, set-top boxes and mobile devices.
