The ICS650R-07 is a versatile digital frequency synthesizer that provides a wide range of applications and can be used as a clock generator, PLL (phase-locked loop), or frequency synthesizer. The ICS650R-07 is capable of generating and controlling frequencies from 1 MHz to 1.5 GHz. It features both pulse-width modulation (PWM) and frequency modulation (FM) outputs, and each output can be configured for either rising or falling edges. Its QFN-40 package enables the product to be used in space-constrained applications.

Introduction

The ICS650R-07 is a digitally programmable frequency synthesizer that is capable of generating, and controlling frequencies ranging from 1 MHz to 1.5 GHz. It is capable of providing frequency outputs with both pulse-width modulation (PWM) and frequency modulation (FM) signals. The product is designed in a QFN-40 package which keeps the size to a minimum and thus ideally suited for applications which need a small form factor. It has a low power consumption with on-chip voltage control including standby and burst modes to extend battery life. Clock outputs are differential, which allows for low jitter and sub-nanosecond level accuracy.

Application Field

Due to its versatile yet cost-effective solution, the ICS650R-07 is suitable for a wide variety of applications. It is specifically designed for high-speed clock generation and frequency control. The device is capable of supplying PWM and FM signals and with its range of frequencies from 1 MHz to 1.5 GHz, it can be used in a number of different areas such as medical, consumer, communications, and automotive markets. It is also ideal for use in a wide range of applications that require precise timing and synchronization. It is particularly well suited for high resolution, low latency video and audio applications as well as applications that require timing or clocking networks.

Working Principle

The ICS650R-07 is a frequency synthesizer that uses a digitally programmable architecture and an advanced finite impulse response (FIR) filter to achieve high frequency accuracy. The device works by establishing the relationship between an input frequency (Fref) and an output frequency (Fout). The input frequency is then used to generate internal signals for controlling the switching of output transistors. The output frequency is calculated based on the settings of several digital registers, including the divider, digital filter, gain, and phase adjust. The device also has digital control and monitoring features with an on-chip bus interface to enable use in removable digital boards.

The device also has a very low jitter output which makes it suitable for applications that require precise timing. Its internal filtering circuitry, combined with digital post-selection and acclimation, ensure the highest possible output frequency accuracy, while the output transistors precisely control the output frequency and power. The device also has a built-in self-calibration function which can continuously monitor and adjust the output frequency as required.

Conclusion

The ICS650R-07 is a versatile and economical frequency synthesizer, capable of providing a wide array of applications in many different markets and use cases. It is very suitable for applications that require both frequency and timing accuracy, thanks to its advanced filter and digital post-selection technologies. Its small form factor and low power consumption, combined with its low jitter output, make it an ideal choice for applications that need accuracy and fast response times. The on-chip bus interface and self-calibration enable easy integration into many different systems.
