SI53314-B-GMR

The SI53314-B-GMR is a low-power, single driver that provides general purpose clock distributions. In this application field, clocks are distributed to multiple devices. The SI53314-B-GMR is suitable for use in multiple applications such as PCIe, Ethernet, USB, and microprocessor systems.

The SI53314-B-GMR is equipped with both a low-skew, programmable clock output and a random clock output. The programmable clock output is generated based on a reference clock supplied to the chip, while the random clock is suitable for use in applications that require more flexibility and lower power consumption. The chip includes two control inputs, one for programming and one for adjusting the spread spectrum clock frequency.

The clock frequencies that can be generated by the SI53314-B-GMR depend on the reference clock. The chip has various output frequencies ranging from 6 to 52 MHz, and the output can be programmed to generate frequencies below 6MHz or above 52MHz by providing an external reference clock. The chip also allows for use of 1:N or 1:N/2 frequency division or spreading of the reference clock.

The SI53314-B-GMR provides a flexible clock-distribution solution for applications with multiple clock sources and different output frequencies. The programmable clock output can be used to create a single clock with the desired frequency while the random clock output provides a low-power alternative option. The chip can also be used to spread clock frequencies over a wide frequency range, depending on the external reference clock.

Regarding the working principle, the SI53314-B-GMR uses a programmable clock-distribution circuit. This circuit is designed to provide the required output frequencies for each application. It uses a crystal oscillator, usually in the range of 25MHz-100MHz, as the reference clock. This reference clock is then programmed via the two control inputs to generate the required output frequencies.

The programmable clock output is generated as a single frequency, while the random clock output is generated over a spread spectrum of frequencies. The spread spectrum clock frequency is adjustable using the control inputs, allowing for flexibility. The chip also features internal filters, allowing it to minimize power consumption while providing the required frequency and stability.

In summary, the SI53314-B-GMR allows for the distribution and integration of multiple clock sources into a single output. It provides flexible timing option with a wide frequency range, adjustable spread spectrum frequency and low power consumption. The chip is suitable for applications in PCIe, Ethernet, USB, and microprocessor systems.
