Functional Description

The CY7B993V and CY7B994V High-speed Multi-phase PLL Clock Buffers offer user-selectable control over system clock functions. This multiple-output clock driver provides the system integrator with functions necessary to optimize the timing of high-performance computer and communication systems.
