Clock Generators, PLLs, Frequency Synthesizers

The SI5335A-B07235-GM is a high-performance clock generator that targets many types of applications and provides excellent flexibility and jitter performance throughout. It is designed to meet the needs of high-speed and high-performance applications, such as communication networks, storage, and video. The device utilizes an integrated Phase-Locked Loop (PLL) capable of generating a wide range of different clock frequencies and signal outputs, making it applicable to many different types of applications.

The SI5335A-B07235-GM PLL consists of a VCO, a programmable divider, a phase detector, and a low-pass filter. It is implemented as an adaptive PLL, meaning it can adjust its parameters depending on the input clock signal. The VCO is powered by an external crystal oscillator, which serves as a reference signal for the phase detector. The programmable divider allows the clock signal to be divided by integers from 1 to 16. The phase detector compares the frequency of the reference signal with the frequency of the divided clock signal, and adjusts the VCO until the two signals match, forming a closed loop system. This allows the device to be used as a frequency synthesizer, generating exact frequencies from signals of varying input frequencies and output rates.

The SI5335A-B07235-GM has many advantages for use in various applications. It can generate up to 7 outputs, each with a programmable output frequency. In addition, the device includes a dynamic frequency adjustment feature, which allows the user to change the output frequencies without the need to power down or reset the device. This is especially useful in applications where frequency adjustments are often needed, such as video and data transmission. The device also features differential outputs, which are better compared to single-ended outputs due to their immunity to common-mode noise.

The main application fields of the SI5335A-B07235-GM are communication networks, storage, and video applications. It is ideal for these types of applications as it does not require a lot of external circuitry, allowing for a smaller form factor, and it is easy to program, allowing for a quick and accurate setup. The frequency synthesis capability of the device makes it an attractive choice for transmitting digital audio or video streams where a specific output frequency is needed.

In summary, the SI5335A-B07235-GM is a versatile and reliable clock generator that provides excellent flexibility and jitter performance. It can easily be used for communication networks, storage, and video applications, due to its frequency synthesis ability and dynamic frequency adjustment feature. With its differential outputs, this device provides an excellent source of clock signals for these types of applications.
