Description Configurable clock output C. Voltage supply. Ground. Reference crystal input or external reference clock input. Reference crystal feedback. Buffered reference clock output. Configurable clock output D. CPU frequency clock output. Configurable clock output B. Configurable clock output A. CPU clock select input, bit 0. CPU clock select input, bit 1. CPU clock select input, bit 2. Optionally enables suspend feature when LOW.[3] Places outputs in three-state[4] condition and shuts down chip when LOW. Optionally, only places outputs in three-state[4] condition and does not shut down chip when LOW.


Notes: 1. For best accuracy, use a parallel-resonant crystal, CLOAD or 18 pF. 2. Float XTALOUT pin if XTALIN is driven by reference clock (as opposed to crystal). 3. Please refer to application note "Understanding the CY2291, CY2292 and CY2295" for more information. 4. The CY2292 has weak pull-downs on all outputs. Hence, when a three-state condition is forced on the outputs, the output pins are pulled LOW.


The is a third-generation family of clock generators. The CY2292 is upwardly compatible with the industry standard ICD2023 and ICD2028 and continues their tradition by providing a high level of customizable features to meet the diverse clock generation needs of modern motherboards and other synchronous systems. All parts provide a highly configurable set of clocks for PC motherboard applications. Each of the four configurable clock outputs (CLKA-CLKD) can be assigned of 30 frequencies in any combination. Multiple outputs configured for the same or related[3] frequencies will have low (<500 ps) skew, in effect providing on-chip buffering for heavily loaded signals. The CY2292 can be configured for either or 3.3V operation. The internal ROM tables use EPROM technology, allowing full customization of output frequencies. The reference oscillator has been designed for to 25-MHz crystals, providing additional flexibility. No external components are required with this crystal. Alternatively, an external reference clock of frequency between 1 MHz and 30 MHz can be used. all other active components. The resulting current on the VDD pins will be less than 50 μA (for Commercial Temp. 100 μA for Industrial Temp.) After leaving shutdown mode, the PLLs will have to re-lock. All outputs have a weak pull-down so that the outputs do not float when three-stated.[4] The S2/SUSPEND input can be configured to shut down a customizable set of outputs and/or PLLs, when LOW. All PLLs and any of the outputs can be shut off in nearly any combination. The only limitation is that if a PLL is shut off, all outputs derived from it must also be shut off. Suspending a PLL shuts off all associated logic, while suspending an output simply forces a three-state condition.[3] The CPUCLK can slew (transition) smoothly between 20 MHz and the maximum output frequency (100 MHz at 5V/80 MHz at 3.3V for Commercial Temp. parts or 90 MHz at 5V/66.6 MHz at 3.3V for Industrial Temp. and for field-programmed parts). This feature is extremely useful in "Green" PC and laptop applications, where reducing the frequency of operation can result in considerable power savings. This feature meets all 486 and PentiumR processor slewing requirements.


The CY2292 has four independent frequency sources on-chip. These are the reference oscillator, and three Phase-Locked Loops (PLLs). Each PLL has a specific function. The System PLL (SPLL) provides fixed output frequencies on the configurable outputs. The SPLL offers the most output frequency divider options. The CPU PLL (CPLL) is controlled by the select inputs (S0-S2) to provide eight user-selectable frequencies with smooth slewing between frequencies. The Utility PLL (UPLL) provides the most accurate clock. It is often used for miscellaneous frequencies not provided by the other frequency sources. All configurations are EPROM programmable, providing short sample and production lead times. Please refer to the application note "Understanding the CY2291, CY2292, and CY2295" for information on configuring the part.


CyClocks is an easy-to-use application that allows you to configure any one of the EPROM-programmable clocks offered by Cypress. You may specify the input frequency, PLL and output frequencies, and different functional options. Please note the output frequency ranges in this data sheet when specifying them in CyClocks to ensure that you stay within the limits. CyClocks also has a power calculation feature that allows you to see the power consumption of your specific configuration. You can download a copy of CyClocks for free on Cypress's website at www.cypress.com.


The Cypress Frequency Timing Generator (FTG) Programmer is a portable programmer designed to custom program our family of EPROM Field Programmable Clock Devices. The FTG programmers connect a PC serial port and allow users of CyClocks software to quickly and easily program any of the CY2292F, CY2071AF, and CY2907F devices. The ordering code for the Cypress FTG Programmer is CY3670.
