Improving Jitter
Jitter Optimization Control is useful in mitigating problems re-
lated to similar clocks switching at the same moment, causing
excess jitter. If one PLL is driving more than one output, the
negative phase of the PLL can be selected for one of the out-
puts (CLKA–CLKD). This prevents the output edges from
aligning, allowing superior jitter performance.
Power Supply Sequencing
For parts with multiple V
sequencing requirements. The part will not be fully operational
until all V
fied in the “Operating Conditions” table.
All grounds should be connected to the same ground plane.
CyClocks RT™ Software
CyClocks RT is our second-generation application that allows
users to configure this device. The easy-to-use interface offers
complete control of the many features of this family including
input frequency, PLL and output frequencies, and different
functional options. Data sheet frequency range limitations are
checked and performance tuning is automatically applied.
CyClocks RT also has a power estimation feature that allows
you to see the power consumption of your specific configura-
tion. You can download a copy of CyClocks RT for free on
Cypress’s web site at www.cypress.com.

Junction Temperature Limitations
It is possible to program the CY22392 such that the maximum
Junction Temperature rating is exceeded. The package
115 C/W. Use the CyClocks RT power estimation feature to
verify that the programmed configuration meets the Junction
Temperature and Package Power Dissipation maximum rat-
ings.
