CY7B9940V-2AC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY7B9940V-2AC is a high-speed multi-frequency PLL clock buffer from the 7B Series. It features eight true outputs and zero inverted outputs, designed for precise clock distribution in complex digital systems. The device utilizes a Phase-Locked Loop (PLL) architecture to generate stable clock signals with low jitter characteristics. It is housed in a 44-pin Plastic Quad Flat Package (PQFP/TQFP) with dimensions of 10 x 10 mm and a height of 1.40 mm. This component supports multiple frequency configurations, making it suitable for applications requiring flexible clocking solutions across various data rates.
