Unmatched Performance

The Si5xx products support frequency ranges from 100 kHz to 1.4 GHz, provide ultra-low jitter performance (<0.3 ps rms typical OC-192) and offer new features previously unavailable in high-frequency oscillators based on SAW resonators or inverted mesa crystals. These features include dual, quad and any frequency operation as well as selectable voltage gain (kV) for VCXO devices.

Highest Reliability

Using Silicon Labs’ DSPLL technology, the Si5xx products offer total frequency stability over time and temperature that is more than five times better than competing SAW devices. Compared to inverted mesa crystal oscillators, Silicon Labs offers a solution that is more mechanically robust while providing five times better aging stability.

Industry’s Shortest Lead Times

Silicon Labs changes the manufacturing model by enabling the shortest and most predictable lead times for high-frequency, low-jitter oscillators. By moving the frequency control and tuning into a mixed-signal IC, complex manufacturing steps are either eliminated or simplified.

Selecting the Optimum PCIe Clock Source

To ensure proper compliance with the PCIe standard, systems require careful attention to the timing subsystem and architecture. This article explores some of the standard clocking architectures for PCIe and considers their benefits for typical system applications, including: clock architecture selection (Common Refclk, Separate Refclk or Data Clocked Refclk), requirements in applications that use FPGAs, jitter performance of the reference clock, use of spread spectrum clocking, and more.

SyncE and IEEE 1588: Sync Distribution for a Unified Network

Since Ethernet or packet based networks operate asynchronously, many of the traditional applications that depend on synchronization are not supported. Designers increasingly need to combine services supplied by data efficient packet networks with the ones served by the large installed base of traditional SONET/SDH networks. Both Synchronous Ethernet (SyncE) and packet timing using the IEEE 1588 protocol offer viable solutions in unifying service delivery over both networks. Download this new app note from Silicon Labs to discover methods for transporting synchronization and potential synchronized timing implementations.

Prototyping with Frequency-Flexible Crystal Oscillators

Developers of new systems ideally should make decisions regarding clocking requirements early in the design process. Although clocking rates are critical parameters that should be known in advance, determining these rates sometimes requires experimentation and re-evaluation. The use of frequency-flexible, programmable crystal oscillators (XOs) as prototyping tools can facilitate the process of validating system performance and help streamline the overall product development cycle.
