CY7B991V-5JC - Brand New Cypress Semiconductor Clock Buffers, Drivers
-
Description
The CY7B991V-5JC is a programmable skew clock buffer that provides user-selectable control over system clock functions. It is designed to optimize the timing of high-performance computer systems by offering functions necessary to improve system performance. With eight individual drivers arranged as four pairs of user-controllable outputs, this clock buffer can drive terminated transmission lines with low impedance. It delivers minimal output skew, specified output levels, and supports both TTL and CMOS logic.
