Clear Clock Circle 3


ClearClock™ PLL-based XOs


Power Optimized 119fs and 125fs Jitter Performance for the Fastest Data Links

The ClearClock™ series expands its offering with the new AX5 XO in a 5x3.2mm footprint for next generation networking and RF applications. This series leads the industry in low power consumption while maintaining typical jitter of 125fs, ideal for clocking serial data links beyond 56Gbps. The AX5 offers a smaller package size required by next generation storage and cloud computing applications, but with the same performance capabilities as the 5x7mm AX7.

The AX7 series is optimized for superior rms jitter performance (119 typ), while consuming 130mW.

The AX7 series features the widest factory configurable frequency range from 50MHz to 2.1GHz in its performance class. Other factory configurable options include supply voltage of 3.3V, 2.5V, or 1.8V with operating temperatures ranging from -20°C to +70°C or -40°C to +85°C with either ±50ppm or ±100ppm all-inclusive frequency stability.
