The ICS7152M-02 clock generator is a highly integrated clock device from Integrated Device Technology Corporation. It is designed to generate 5 different frequencies from one single reference frequency. The device is primarily used for communication systems, such as mobile and wireless networking. The ICS7152M-02 can be used to generate multiple system-level frequencies from a single reference clock, thereby simplifying system design and providing system-level cost savings.

The ICS7152M-02 utilizes the Hyper-Integrated Multi-Function Clock (HYMFC) technology to provide a synchronous oscillator, frequency synthesizer, phase-locked loop (PLL), and digital isolation all in a single device. This highly integrated device is capable of generating five independent system-level frequencies and provides a clock source that is accurate and reliable due to the HYMFC technology.

Working Principle

The ICS7152M-02 consists of a high-integrity oscillator, phase-locked loop (PLL), and frequency synthesizer. The oscillator generates an output frequency from a single reference clock. This signal is then passed to the PLL which locks the signal to the input reference clock and then passes it to the frequency synthesizer. The frequency synthesizer then generates multiple output frequencies that can be used for system synchronization, to reduce system parts count, and to reduce system cost.

The ICS7152M-02 can be used for multiple sensing applications, such as wavelength division multiplexing (WDM), optical transport networks (OTN), Ethernet, and 4G/5G mobile communication systems. The device is capable of generating five independent output frequencies between 100MHz and 1GHz from a single reference frequency, thereby eliminating the need for multiple system-level oscillators. Additionally, the device features digital isolation, which ensures low spurious emissions and high reliability.

Features

The ICS7152M-02 offers a wide range of features aimed at providing reliable and accurate timing and synchronization in communication systems. It offers a wide range of input reference frequencies, from 10 MHz to 40 MHz, to simplify system level design and provide cost savings. Additionally, the device supports input clock sources of 1PPS, or 10 MHz, both of which can be used to reduce system parts count and cost. The device also provides a per output channel phase noise of -112 dBc/Hz, and a frequency accuracy of ±100 ppb.

The device also supports a range of output options, such as LVDS, LVPECL, and multi-mode CMOS. Additionally, it offers different levels of output drive strength, from 5mA to 22mA, allowing the user to customize the output strength and power consumption levels to optimize system efficiency. Furthermore, the device features chip select pin and phase shift control pin, which can be used for power suppression and for implementing active clock gating for better system power efficiency.

Applications

The ICS7152M-02 is ideal for applications that require accurate and reliable synchronization of multiple frequencies from a single reference clock. The device is ideal for wireless and mobile communication systems, optical services, and Ethernet applications. Additionally, the device is used in modern data processing, storage and network systems, including storage area networks (SANs) and high-performance computing (HPCs).

In summary, the ICS7152M-02 is a high-integrity clock generator suitable for a range of applications. It combines a synchronous oscillator, frequency synthesizer, phase-locked loop (PLL) and digital isolation into a single device to generate multiple system-level frequencies from a single reference clock. The device offers a range of features, such as low-spurious emissions and wide frequency range, making it ideal for timing and synchronization applications. Additionally, it offers a range of output options, allowing for further customization of the output drive strength and power consumption levels to optimize system efficiency.
