Notes
1. For best accuracy, use a parallel-resonant crystal, CLOAD  17 pF or 18 pF.
2. Float XTALOUT pin if XTALIN is driven by reference clock (as opposed to crystal).
3. The CY2292 has weak pull downs on all outputs. Hence, when a tristate condition is forced on the outputs, the output pins are pulled low.

CY2292
Operation
associated logic, while suspending an output simply forces a
tristate condition.
The CY2292 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.
The CPUCLK can slew (transition) smoothly between 20 MHz
and the maximum output frequency (100 MHz at 5 V / 80 MHz at
3.3 V for commercial temperature parts or 90 MHz at
5 V / 66.6 MHz at 3.3 V for industrial temperature and for
field-programmed parts). This feature is extremely useful in
green applications, where reducing the frequency of operation
can result in considerable power savings.
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 1 of 30 frequencies in
any combination. Multiple outputs configured for the same or
related frequencies have low (less than 500 ps) skew, in effect
providing on-chip buffering for heavily loaded signals.
The CY2292 can be configured for either 5 V or 3.3 V operation.
The internal ROM tables use EPROM technology, allowing full
customization of output frequencies. The reference oscillator is
designed for 10 MHz 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.
Output Configuration
The CY2292 has four independent frequency sources on-chip.
These are the reference oscillator and three 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.
Power Saving Features
The SHUTDOWN/OE input tristates the outputs when pulled
LOW. If system shutdown is enabled, a LOW on this pin also
shuts off the PLLs, counters, the reference oscillator, and all
other active components. The resulting current on the VDD pins
is less than 50 µA (for commercial temperature or 100 µA for
industrial temperature). After leaving shutdown mode, the PLLs
have to relock. All outputs have a weak pull down so that the
outputs do not float when tristated.[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
CyClocks Software
CyClocks is an easy-to-use application that allows you to
configure any one of the EPROM-programmable clocks offered
by Cypress. Specify the input frequency, PLL and output
frequencies, and different functional options. Note the output
frequency ranges in this datasheet 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. CyClocks is a sub
application located within the CyberClocks software. You can
download a copy of CyberClocks for free on the Cypress web site
at http://www.cypress.com.
Cypress FTG Programmer
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
programmer connects to a PC serial port and allow users of
CyClocks software to quickly and easily program any of the
CY2291F, CY2292F and CY2907F devices. The ordering code
for the Cypress FTG Programmer is CY3670. An adapter, the
CY3095, connects to the CY3670 and is required for
programming the CY2292F.
Custom Configuration Request Procedure
The CY229x are EPROM-programmable devices that may be
configured in the factory or in the field by a Cypress field
application engineer (FAE). The output frequencies requested is
matched as closely as the internal PLL divider and multiplier
options allow. All custom requests must be submitted to your
local Cypress FAE or sales representative. The method to use to
request custom configurations is:
Use CyClocks software. This software automatically calculates
the output frequencies that can be generated by the CY229x
devices and provides a print-out of final pinout which can be
submitted (in electronic or print format) to your local FAE or sales
representative.
When the custom request is processed, you receive a part
number with a 3-digit extension (for example, CY2292SC-128)
specific to the frequencies and pinout of your device. This is the
part number used for samples requests and production orders.
Note
4. The CY2292 has weak pull downs on all outputs. Hence, when a tristate condition is forced on the outputs, the output pins are pulled low.

6. External input reference clock must have a duty cycle between 40% and 60%, measured at VDD / 2.
7. Refer to white paper “Crystal Oscillator Topics” for information on AC-coupling the external input reference clock.
8. The oscillator circuit is optimized for a crystal reference and for external reference clocks up to 20 MHz. For external reference clocks above 20 MHz, it is recommended
that a 150  pull up resistor to VDD be connected to the Xout pin.
