CY2412SXC-3T clock generator is a highly integrated device, specifically designed for mobile and consumer applications. It is ideal for portable products that require very low power consumption, accuracy and wide operating temperature range between -40°C to +85°C.

The CY2412SXC-3T is well suited for applications in the consumer space, such as Set-top boxes, DVD Players, HDTVs, Cameras, Portable Media Players, etc.

The CY2412SXC-3T is a fully integrated clock generator solution with dual synthesizers, low power consumption, high accuracy and excellent EMI performance. It is the first device to combine dual PLLs with RMS-to-DC conversion, periodic jitter filtering, ultra-low power Fractional-N synthesizers, multiple output dividers and control logic into a single device. It also offers programmable frequency, duty cycle and output voltage.

CY2412SXC-3T operates on 3V core supply and is available in a RoHS-compatible 20-pin SSOP package. It includes three main components: Synthesizer, RMS-to-DC Converter and Control Logic. In addition, the device features a frequency select pin.

Synthesizer

The CY2412SXC-3T synthesizer has two independent operating ranges, normal and high-frequency. The normal range supports up to 54.6 MHz and the high-frequency range supports up to 108 MHz. Both ranges include fractional-N synthesis with 0.001 Hz resolution.

The synthesizers use a proprietary digital frequency control scheme that allows for programmable frequency, duty cycle and output voltage. The high-frequency range includes a built-in filter that reduces numerical phase noise. The high-frequency range also includes a programmable jitter filter for improved emissions.

RMS-to-DC Converter

The CY2412SXC-3T contains a built-in RMS-to-DC converter that converts the input clock signal from the synthesizer into an analog control voltage. The output of the converter is used to adjust the frequency of the output signals. This feature allows the device to accommodate different clock inputs and preserve the frequency stability.

Control Logic

The CY2412SXC-3T also includes a set of control logic that controls the output clocks of the device. The control logic allows the user to select the output frequency, duty cycle and output voltage.

Conclusion

The CY2412SXC-3T is ideal for applications that require very low power consumption, accuracy and wide operating temperature range between -40°C to +85°C. It combines dual synthesizers, a low power consumption, high accuracy and excellent EMI performance into one device. The device is suitable for a variety of consumer applications, such as Set-top boxes, DVD Players, HDTVs, Cameras, Portable Media Players, etc. It is housed in a RoHS-compatible package and operates on 3V core supply.
