Product Summary
The CY7B991V-2JC is a Low voltage Programmable Skew Clock Buffer. The CY7B991V-2JC offers user-selectable control over system clock functions. These multiple-output clock drivers of the CY7B991V-2JC provide the system integrator with functions necessary to optimize the timing of high-performance computer systems. Each of the eight individual drivers, arranged as four pairs of user-controllable outputs can drive terminated transmission lines with impedances as low as 50Ω. These delivers minimal and specified output skews and full-swing logic levels.
