Programmable Oscillators are widely used in many applications thanks to their many features and flexible nature. One of these oscillators is the SIT9005ACR2G-33SC, which is a frequency synthesizer that features two independent outputs of both a square wave and a sine wave. Additionally, the unit has programmable frequency resolution, phase align, output selection, power-on reset, and output clock phase shift.

The SIT9005ACR2G-33SC is particularly useful for use in consumer electronic applications that require precise timing control signals and ultra-low power consumption. Specifically, this oscillator is suitable for use in TVs, set-top boxes, portable audio and other consumer audio-visual equipment. Furthermore, it is a good fit for PC motherboards and other computer peripheral components that require advanced timing control.

In terms of performance, the SIT9005ACR2G-33SC is capable of operating at up to 1.2 GHz and can provide an accuracy of ±200 ppm with a frequency resolution of 0.4Hz. It also offers an extended temperature range of -40°C to +85°C and has a low power consumption of 10 mW typically. The unit is constructed using a CMOS process and features a low static current of 1.6 µA.

At the core of the operation of the SIT9005ACR2G-33SC is a phase-locked loop system. This system has a voltage-controlled oscillator (VCO) which is used to generate the desired frequency output. The phase-locked loop works by utilizing a phase detector, which compares the phase of the input clock with the output frequency of the VCO. If the two signals are not in-phase, the phase detector will output an error signal, which is then amplified and sent back to the VCO in order to adjust its frequency. This process continues until the input clock and output frequency of the VCO become in-phase. As a result, the output frequency of the VCO will remain locked or “locked-in” to the input clock.

The SIT9005ACR2G-33SC has several additional features that make it particularly useful for consumer electronics applications. It has a divide-by-16 programmable prescaler and a divide- by-32 programmable postscaler to further reduce the frequency output. Additionally, it has both a programmable phase align and output selection feature which are useful for ensuring that the output is in-phase with the input clock. Finally, the unit also features a power-on reset to ensure that the clock is reset upon turning on a device and a programmable output clock phase-shift which is useful for reducing the potential of EMI.

In summary, the SIT9005ACR2G-33SC offers high performance and flexibility for consumer electronics applications. It has a wide operating range up to 1.2 GHz with an accuracy of ±200 ppm and a low static current of 1.6 µA. It also features a programmable frequency resolution, power-on reset, phase align, output selection, and output clock phase shift for additional control. As a result, this oscillator makes a great addition to any setup that requires the highest levels of accuracy and performance.
