CY2292 is a three PLL general-purpose EPROM programmable clock generator, which features low-skew, low-jitter, high-accuracy outputs, power-management options, frequency select option, smooth CPUCLK slewing, configurable 3.3V or 5V operation.
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.
| Supply Voltage (5 V operation) | 5.0 V (typical 5.5 V) |
|---|---|
| Supply Voltage (3.3 V operation) | 3.3 V (typical 3.6 V) |
| Output Frequency Range (5 V, commercial) | 76.923 kHz – 100 MHz |
When pulled low, SHUTDOWN/OE three‑states all outputs and shuts off the PLLs, counters, reference oscillator and other active circuitry.
The CPU PLL provides eight user‑selectable frequencies.
Cypress provides the CyClocks™ application for configuring and programming the CY2292 devices.
The maximum output frequency is 100 MHz at 5 V for commercial‑temperature devices.
