SI53102-A3-GMR is a clock generator for use within high-speed transmission applications, designed to contain all the necessary components for a complete clocking system solution. It features both low jitter and low power consumption for a range of optical module designs. The SI53102-A3-GMR is ideal for applications such as 10 Gb/s Ethernet and 10 Gb/s Fibre Channel.

The SI53102-A3-GMR meets the latest EMC requirements and is compliant to the latest requirements as set out in the ITU-T G.729 and G.726 communications standards. It also meets the SONET/SDH adaptation layer requirements as set out in GR-209-CORE.

The SI53102-A3-GMR consists of four components: the CMOS Clock Generator, the Digital PLL, and two clock dividers. The CMOS Clock Generator produces a base frequency of 15MHz. The Digital PLL circuit is used to generate a continuously adjustable clock frequency from 0.7MHz to 15MHz. The two clock dividers are integrated to divide the clock signal down to frequencies of 19.2KHz, 1KHz and 0.2KHz.

The SI53102-A3-GMR has many advantages, including low power consumption and light weight. It is suitable for short-distance and long-distance transmission applications, and can eliminate the costs associated with external clock oscillators. In addition, it is low-jitter and able to support high data rate transmission. Furthermore, the SI53102-A3-GMR is completely programmable, allowing it to be adjusted to any needed frequency and output level.

The working principle of SI53102-A3-GMR is as follows: The CMOS Clock Generator produces a base frequency which is then converted to a low-distortion, high-frequency clock by the Digital PLL Circuit. This clock signal is then divided down by the internal clock dividers in order to output different frequencies. These outputted frequencies are converted back to low-jitter, low-power clock signals that can be used by the optical module.

In summary, the SI53102-A3-GMR is an excellent clock generator for use in high-speed transmission applications, with efficiencies such as a low power consumption and compact size. It meets all of the latest EMC and ITU-T standards and is programmable to any required frequency. The working principle is straightforward and efficient, with the CMOS Clock Generator producing a base frequency and the integrated Digital PLL and clock dividers dividing and outputting different frequencies depending on the optical module’s requirements.
