The SI5356A-B05090-GMR is a clock generator or frequency synthesizer. It is designed to operate at a maximum frequency of up to 560 MHz, and its applications include telecommunications, digital imaging, and industrial automation. The device has two different modes of operation; a pulse frequency (Pf) mode, and a fractional-N (Fn) mode.In Pf mode, SI5356A-B05090-GMR integrates the output frequency which is determined accordingly. This mode is suitable for digital communication applications, such as Ethernet, ASDL and Wi-Fi, as well as digital image processing, and HDTV. In the Fn mode, SI5356A-B05090-GMR can output highly precise clocks with a high degree of jitter reduction. This mode is employed for WiGig and cellular communication base stations, as well as for data processing and ASIC design.The SI5356A-B05090-GMR is a highly advanced device that operates in a single voltage mode, providing exceptional low-jitter performance. This device includes an input buffer which allows the user to easily set the input frequency and achieve higher accuracy. The input buffer also allows for sensitive monitoring of the reference clock without disturbing the oscillator.The SI5356A-B05090-GMR is equipped with a variety of features such as adjustable output drive, power up and down sequencing with smooth ramps, manual or programmable turn-on and turn-off times and an adjustable slew rate. This device also features an on-board temperature monitor, allowing the user to keep track of the temperature range and ensure proper operation.The SI5356A-B05090-GMR utilizes a phase-locked loop (PLL) to generate the desired clock frequencies. The PLL works by comparing the desired clock frequency with the actual clock frequency and then trying to match the two, thus eliminating the phase-difference between the two signals. The PLL is composed of three main components, the reference clock, voltage controlled oscillator and the loop filter.The reference clock source is a real-time clock generator and a crystal oscillator. The crystal oscillator provides the clock signal for the reference clock source. The voltage-controlled oscillator (VCO) is used to generate the output clock frequency and allows for the adjustment of frequency and duty cycle. The VCO is composed of a pair of cross-coupled transistors and is controlled by an external signal, such as a square waveform from a pulse-width modulation (PWM) signal. Finally, the loop filter is used to reduce the phase-noise and keep the PLL stable.The SI5356A-B05090-GMR is designed to deliver exceptional performance with outstanding features that make it ideal for a wide range of applications. It is designed as a commercial-grade product with highly reliable and accurate clock solutions. This device is compact, cost-effective and provides exceptional features, making it an ideal choice for many applications.
