  •  Subrate clock for easy generation of reference clock

The transfer of large amounts of data and spiraling transmission rates, needed for services such as video on demand and to ensure ever  increasing Internet bandwidth, are driving speed increases in infrastructure and components. Signals break through one performance barrier after another. As electrical signals start competing with laser-generated ones, it is no longer necessary to convert to optical to reach high speeds.

High-speed protocols rely on a solid physical layer and dependable signal integrity. The next generations of protocols such as PCI Express, which in its second-generation doubles both clock rate and data throughput, raise the standards for jitter and sensitivity. Validation and characterization become critical in ensur-ing effects such as reflection and crosstalk are kept within allowable limits.

As a developer you strive to keep pace with faster and more complex bus standards. Accelerated development cycles make proprietary test solutions less attractive. Instead you need standard instruments you can rely on to accomplish the job you need to get done. There can be no compromise on data quality, timing, synchronization and control.
