Analog Devices' Launches New Clock Circuit Design And Simulation Tool

Norword, MA -- Analog Devices, Inc. announced the availability of its new ADIsimCLK clock IC design and simulation tool, along with the addition of three new clock ICs to its growing portfolio of clock products. ADIsimCLK offers clock and timing engineers a simulation tool for designing and analyzing clock circuits used in a broad range of applications, such as wireless transceivers, broadband infrastructure, medical imaging, general instrumentation, and automated test equipment. By using the tool's tutorials, design wizards, and data entry screens, engineers can now create complete, robust timing solutions. And because ADIsimCLK models the phase noise and jitter of the components used, final system performance can be predicted, allowing designers to move from simulations to final board layouts.

The availability of ADIsimCLK coincides with the introduction of Analog Devices' newest clock IC family members - the AD9513, AD9514 and AD9515 - that extend output clock rates to 1.6 GHz. The new pin-programmable ICs feature high integration in small packages. Like preceding members of Analog Devices' AD95xx clock family, the new clock ICs feature low jitter performance which can improve SNR (signal-to-noise ratio) by 6 to 12 dB in wireless infrastructure, instrumentation, and broadband networking systems.

"Use of low-phase-noise, low-jitter clock ICs reduces overall noise in a signal path," said Kevin Kattmann, product line director, High Speed Converters, Analog Devices. "However, optimizing clock solutions can be painstaking and time consuming. The ADIsimCLK tool was created to simplify the clock distribution design process by allowing customers to analyze and test critical timing circuits before committing to hardware, reducing risk and shortening development time. The ICs introduced today help customers who need a better way to distribute low jitter clocks across a crowded PCB to multiple sub-circuits. Customers can now route common clock frequencies up to 1.6 GHz to the AD9513/14/15, which perform divides, phase offsets, and delays in close proximity to the circuits needing clocks. The small packages allow customers to save on board space and cost, while improving their overall system performance."
