The SI5350C-B03328-GTR is a feature-rich, low pin-count clock generator that interfaces directly with high-speed SerDes protocols. This family of clock synthesizers offers a broad selection of high-performance level 1 jitter clean output clocks to enable asynchronous operation of high-speed data links. This device is able to provide output clock frequencies up to 3.2GHz with over 1500 frequency plan options, making it a versatile product for several applications. This clock synthesizer uses two integrated PLLs, along with an on-chip voltage controlled oscillator (VCO), to generate multi-channel output clocks with programmable output frequencies.

The SI5350C-B03328-GTR is best suitable for applications where precise clock signal generation and fast switching between different clock frequencies are required. It is ideal for telecommunications, servers and storage, and high-speed networks, as well as digital video and audio products. The device supports data rates up to 10 Gbps, thus eliminating the need of external buffering or multiplexing, thus reducing overall system cost. The device is also able to provide jitter attenuation and signal integrity improvements via its programmability.

The SI5350C-B03328-GTR works on the principle of using an on-chip VCO and two PLLs to generate precise frequencies without the need of an external crystal or VCXO. The on-chip VCO frequency is divided by an internal divider to generate the reference frequency for the PLLs. The PLLs are then used to generate the desired output frequencies, with each PLL providing up to seven output frequencies. This allows for easy control of the output signals from the device, as well as the elimination of multiple external components.

One of the other features of the SI5350C-B03328-GTR is its integrated jitter cleaner, which is able to reduce jitter levels down to 0.3ps. This provides significant improvements in signal integrity compared to other clock sources. Additionally, the jitter cleaner is programmable, meaning that it can be tuned to provide better performance under different conditions.

Overall, the SI5350C-B03328-GTR is an ideal solution for applications where precise clock synchronizations and fast switching between different frequencies are required. The on-chip VCO, along with the integrated PLLs, offer a versatile clock source with a wide range of programmable output frequencies up to 3.2GHz. The integrated jitter cleaner ensures signal integrity and improves clock performance, allowing for reliable operation in a variety of applications.
