Cypress CY2292 Three-PLL EPROM Programmable Clock Generator User Manual
The CY2292 is a three‑PLL, EPROM‑programmable clock generator that can be configured for 3.3 V or 5 V operation. It offers up to three custom output frequencies, eight user‑selectable CPU PLL frequencies, and low‑skew, low‑jitter outputs suitable for PC motherboards and other synchronous systems.
The document provides pin configurations, power‑saving features such as SHUTDOWN/OE and S2/SUSPEND, software tools (CyClocks™ and the Cypress FTG Programmer) for programming, and extensive electrical and switching characteristics, including maximum ratings, output jitter, and package diagrams.
