The world of electronics today is constantly advancing, with more precise and accurate devices making it easier for precision operations, as well as cutting down on costs and time conventionally used by such operations. Such high degree of accuracy and precision is made possible by the use of carefully-designed clocked timing systems. One such system is the Silicon Labs SI5319C-C-GMR, an application-specific clock generation and distribution module. Developed for high-precision, high-frequency applications, it is designed to provide low jitter, low skew and robust clock delivery for complex network and data applications.

The SI5319C-C-GMR provides a flexible and reliable timing solution for complex network and data applications such as high-speed Ethernet, SONET/SDH, Fibre Channel, DATA-OVER-SONET/SDH, PCI Express and Serial ATA. It supports the distributed clock synchronization in Crystal-Less designs where no high-speed crystals and oscillators are used. This makes the SI5319C-C-GMR an ideal choice for applications requiring low cost and space-saving solutions.

The core of the SI5319C-C-GMR is a clock-timing synchronizer that allows for a wide range of flexible and complex clock combinations, ensuring a perfect performance in applications requiring multiple frequency and rate clocks. The device uses a clocked-timing technology that is known as Grid Multiplied Reference (GMR) Technology. This technology enables the SI5319C-C-GMR to synchronize any number of clocks and clock signals together, while maintaining low jitter and skew. This makes it an ideal choice when dealing with complex and intolerant clock networks, where highly precise and reliable timing is essential.

As a network or data application may require numerous clocks with varying frequencies, the SI5319C-C-GMR can work with up to 16 unique clock frequencies at any given time. This allows the SI5319C-C-GMR to precisely generate, deliver and synchronize an unlimited number of clock outputs from a single input reference. Additionally, the clock synchronizer is capable of providing absolute accuracy of +100 picosecond (ps) jitter, making it the ideal choice for jitter-sensitive applications.

The SI5319C-C-GMR also offers a variety of input options, from differential and single-ended to I2C, that allows for compatibility with a wide range of existing and legacy clocks. The two integrated PLLs ensure a wide range of reference input options that help reduce Total Harmonic Distortion (THD), making the SI5319C-C-GMR an ideal choice for audio application. It also features input and output feedback support, allowing for greater flexibilities with multiple clock synchronization and delivery.

The SI5319C-C-GMR also provides an Error Monitoring and Recovery (EMR) system that allows for continuous check and maintenance of clock performance. This is aided by a on-chip temperature monitoring system that allows for real-time operation due to the fact that temperature-induced changes in frequency or jitter will be compensated in real-time. This ensures a highly stable and reliable performance even under constantly changing conditions.

Power efficiency is taken into account as well, being designed with a low current consumption of typically 0.4 mA. The SI5319C-C-GMR is also designed with a generated clock output that is immune to supply noise, as it is capable of providing an output clock from a single supply voltage. It is also highly efficient at power savings due to the capacity to distribute and synchronize clocks from a single reference source.

For those needing an efficient, low cost and spance-saving solution for reliable synchronized clock delivery, the Silicon Labs SI5319C-C-GMR is an ideal choice. Its robust design and exceptional features make it the perfect choice for precision timing in complex network and data applications, allowing for unparalleled accuracy and precision.
