Functional Description

The CY7B991V 3.3 V RoboClock® 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 50 Ω. This delivers minimal output skews and full-swing logic levels (LVTTL).
