Product Summary
The CY7B991V-5JI Low voltage Programmable Skew Clock Buffer (LVPSCB) offers user selectable control over system clock functions. These multiple output clock drivers provide the system integrator with functions necessary to optimize the timing of high-performance computer systems. Each of the eight individual drivers, arranged in four pairs of user controllable outputs can drive terminated transmission lines with impedances as low as 50Ω. The CY7B991V-5JI delivers minimal and specified output skews and full swing logic levels (LVTTL).
