ICS7152MI-12 is a Clock/Timing - Clock Generators, PLLs and Frequency Synthesizers. The device is designed for applications like analog to digital (A/D) converters, digital signal processors (DSPs) and microprocessors. The ICS7152MI-12 is a complete clock synthesizer that includes an integrated on-chip programmable PLL, integrated on chip mixers, buffers, and 72-pin low-profile PQFN package.

The ICS7152MI-12 contains an adjusted output channel and a flexible interface. The output channel supports multiple frequencies from both the on-chip numeric-controlled oscillators (NCOs) and up to two external clock sources. This allows a wide range of frequencies to be supported—from 2 Hz to 12 GHz. The flexible interface allows the output channel to be externally controlled or programmed.

The ICS7152MI-12 outputs single frequency sine or differential clock signals with an adjustable jitter performance. The output signal frequency can be programmed using an external synchronized source, or it can be configured using internal control registers. The frequency range is programmable and the number of output channels can be programmed. Additionally, the device is capable of synchronizing the output signal to an external reference clock signal.

The ICS7152MI-12 includes a programmable PLL, which allows for the adjustment of the device\'s output clock frequency. The PLL can be used for applications such as frequency hopping, jitter cleanup, and as a clock generator for design and operation of digital logic circuits. The PLL consists of a VCO, an output frequency divider, and a phase-frequency detector.

The VCO of the PLL uses an on-chip oscillator and an external clock reference to generate an output frequency that is divided down to the desired output frequency. The output frequency divider divides the output frequency by a programmed amount, resulting in a single stable frequency output. Finally, the phase-frequency detector reads the phase difference between the output and the reference clock signal and output the error signal to the VCO. This error signal is then used to adjust the output frequency to match the reference clock.

The ICS7152MI-12 also includes a self-calibration feature. This feature allows the device to be calibrated to track variations in temperature and operating conditions. The self-calibration feature also ensures that the output signal is synchronized to an external reference clock signal.

The ICS7152MI-12 is a complete clock synthesizer. It includes an integrated on-chip programmable PLL, a flexible interface, an adjustable output channel, and a self-calibration feature. This makes it ideal for applications like A/D converters, digital signal processors, and microprocessors. The device also offers multiple frequencies from both the on-chip numeric-controlled oscillators (NCOs) and up to two external clock sources, making it suitable for a wide variety of applications. Additionally, the PLL allows for the adjustment of the output frequency, making it perfect for frequency hopping and jitter cleanup applications. Finally, the self-calibration feature makes it ideal for applications requiring synchronizing the output to an external reference clock signal.
