ClearClock™ Low Jitter XO Solutions

CLEARCLOCK™ Crystal Oscillators

Power-Optimized Jitter Performance for the Fastest Data Links

The ClearClock™ family of oscillators supports the next generation of bandwidth requirements for communications, cloud computing, storage, and RF applications. These oscillators lead the industry in low power consumption while maintaining typical jitter as low as 80fs. They also deliver phase noise performances that FPGAs and ICs require for serial data rates beyond 56Gbps. The ClearClock™ family includes phase locked loop and third overtone solutions offered in compact package sizes as small as 3.2 x 2.5 mm.


PLL-Based ClearClock Solutions


The AX7 series is optimized for superior rms jitter performance (119 typ), while consuming 130mW. The AX7 features the widest factory configurable frequency range from 50MHz to 2.1GHz in its performance class.


The AX5 series is available in a smaller 5 x 3.2 mm 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.


Third Overtone ClearClock Solutions


Typically consuming 30mW of power at the lowest operating voltage of 1.8V, the new AX3, AK5 and AK7 series deliver industry-leading low power consumption for low noise differential oscillators. The devices' simplified third overtone architecture avoids phase locked loop (PLL) based multiplication, reducing overall power consumption far below other high performance XO alternatives.
