On January 9, 2015, Micrel Korea (CEO Oh Young-jun, www.micrel.com), a leading industry player in high-performance linear and power solutions as well as LAN, timing, and communication solutions, announced the supply of the PL902xxx series, a low-power and small form factor high-performance OTP-based jitter attenuator. This device is one of Micrel's JitterBlocker series, a family of factory-programmable jitter attenuation products. The JitterBlocker product family is capable of handling all deterministic jitter, thereby improving not only peak-to-peak jitter but also cumulative jitter and phase noise. The PL902xxx series can reduce jitter on the order of thousands of picoseconds by using clocks below approximately 100ps peak-to-peak level, enabling the use of this clock in various diverse applications.

The PL902xxx device operates on a single 2.5V or 3.3V supply voltage with very low power consumption. It is provided in a compact SOT23 package to enable application to diverse applications, and the programmable I/O pins can be configured as output enable (OE), configuration select (CSEL), power down (PDB) input, and CLK1(2) output. When the PL902xxx power shutdown function is enabled, the IC consumes less than 10μA of power, and through programming flexibility, it can filter any clock frequency up to a maximum of 200MHz. Additionally, the operating temperature range extends from –40°C to +85°C and complies with GREEN/RoHS specifications.

This product family is applicable to various applications including IEEE 1588 GPIO clock cleanup and FPGA-generated clock cleanup, 1/10/40/100 gigabit Ethernet, SONET/SDH, PCI Express, CPRI/OBSAI wireless base stations, optical channels, and SAS/SATA, DIMM, and the like.
