CY7B991-5JC General Description

The CY7B991-5JC from Cypress Semiconductor is a top-of-the-line 1-to-10 clock distribution chip that is designed for high-speed applications where precision timing is crucial. Featuring 10 identical outputs, this chip ensures that input clock signals are distributed with minimal skew, providing a synchronized and stable clock across all connected components. With a supply voltage of 5 volts, it delivers exceptional noise immunity and jitter performance, making it ideal for use in telecommunications, networking, and high-performance computing systems. The maximum propagation delay of 5.5 ns guarantees efficient distribution of clock signals, maintaining timing integrity even in complex electronic systems. Housed in a 28-pin PLCC package, the CY7B991-5JC is easy to integrate into various circuit designs, offering a reliable solution for demanding clock distribution requirements
