Pearl Semiconductor is developing a complete full-breadth of timing products based on its patented SpurFree™ technology to serve all verticals of the datacenters connectivity market. Next-Generation datacenters connectivity standards require Ultra-Low Noise Timing Solutions with outstanding spur-free phase noise behavior and extremely low integrated phase jitter, typically 90 fs spur-inclusive. Our portfolio is designed to meet these demanding requirements and includes various families of programmable reference clocks, clock generators, clock buffers, and jitter attenuators.

The PRL51X is a Quartz Crystal based Ultra-Low Noise Programmable Any-Rate Family of XOs, VCXOs and Tight Stability XO (TS-XO). This family is based on Pearl's patented SpurFree™ Technology, delivering outstanding spur-free phase noise and extremely low integrated phase jitter. With an integrated jitter of 83 fs for frequencies up to 3000 MHz and stability of ±3 ppm in TS-XO mode, the PRL51X is designed for high-performance applications in demanding environments. It comes in a proprietary plastic package that integrates the CMOS die and the quartz crystal, offering superior performance and reliability.

The PRL50X is an Ultra-Low Noise Extended Temperature Crystal Oscillator (XO) specifically tailored for the growing market of Optical Pluggables, Active Electrical Cables (AECs), and Optical Communication. It leverages Pearl's SpurFree™ technology to achieve an outstanding noise performance of 70 fs RMS typical jitter. The PRL50X offers an extended operating temperature range from -40°C to +105°C, with a temperature compensation option for tight stability of ±3 ppm. This low-power device comes in a small 2520 (2.5 mm x 2.0 mm) all-plastic package, integrating the crystal and oscillator chip for optimal performance in space-constrained applications.
