A clock generator and PLL (Phase-Locked Loop) are among the most important components in any chip or system. The SI5335A-B04068-GMR is one such clock generator from Silicon Laboratories that are designed for a wide range of applications, including computing, communications, consumer electronics and storage. The device is suitable for any number of applications, from triggering sampling requests to providing timing to embedded processors and circuits. In this article we will look at the SI5335A-B04068-GMR and how it can be used in your application.

Features of the SI5335A-B04068-GMR

The SI5335A-B04068-GMR provides a range of features which make it an ideal choice for a variety of applications. First and foremost it is a compact device measuring only 3mm x 4mm in size. Despite this small form-factor it still supports a wide range of frequencies and operating voltages, from 0.75 to 5.5V. It can be powered with a range of supplies, including 3V, 3.3V, 5V and 12V. The SI5335A-B04068-GMR also features an integrated phase-locked loop (PLL) with a very wide operating range of around 1200 KHz to 0.6GHz.

The output of the SI5335A-B04068-GMR can be configured in two different ways, either as a PLL Multi-Output (PMO) or as a Phase-Frequency Detector (PFD) output. The PMO output has a higher accuracy than the PFD output and can be used to generate signals up to 400MHz. The PFD output, on the other hand, is limited to frequencies of around 80MHz but is still suitable for a wide range of applications.

The device features a very low jitter of <10ps RMS and can be configured in either a autonomous or a synchronous mode. It also has a very low power dissipation of just w0.4mW, making it an ideal choice for applications where low power is key.

SI5335A-B04068-GMR\'s Application Field

The SI5335A-B04068-GMR can be used in a wide range of applications, including communications, computing, consumer electronics and storage. In communications it can be used to trigger sampling requests in multi-rate systems, such as GSM and EDGE, and it can also be used to generate timing and/or synchronization signals in radio transmitters and receivers. In computing it can be used to provide timing to embedded processors, memory and other peripherals. In consumer electronics it can be used to generate timing signals for televisions, DVD players and other consumer electronics devices. In storage it can be used to generate read/write clock signals in hard drives and other storage devices.

SI5335A-B04068-GMR\'s Working Principle

The SI5335A-B04068-GMR utilizes a phase-locked loop (PLL) to generate its output. A PLL essentially consists of two parts: an oscillator and a phase detector. The oscillator, in this case a crystal oscillator, generates a signal of a fixed frequency. The phase detector then compares the phase of this signal to the phase of an external signal (usually a reference clock signal), and the output is used to adjust the frequency of the oscillator until the two signals are "in phase".

In order to achieve the maximum frequency range and best output accuracy, a range of adjustable parameters is available. These include the Input frequency, Output frequency and Divider/Multiplier ratios, as well as a range of other more advanced settings. All these can be adjusted using a ZIFMC (Zero Insertion Force MCU) or using Silicon Labs\' USB based programming and testing accessories.

The SI5335A-B04068-GMR is a highly integrated clock generator and PLL that is designed for a wide range of applications. Its small size, low power consumption, wide frequency range and low jitter make it ideal for a variety of applications, from generating timing for embedded processors to triggering sampling requests in communications equipment. By leveraging Silicon Laboratories\' programming and testing accessories, users are also able to configure the device to their exact requirements, making it a truly flexible, high-performance clock generator and PLL.
