CLOCKS AND BUFFERS
Cypress’s broad portfolio of silicon-based clock generators and buffers offers the best in class performance in jitter, power, speed, integration,
and package. The portfolio includes single- and multi-PLL programmable clock synthesizers, programmable skew, programmable XO,
VCXO, EMI reduction clocks, zero delay, and fanout buffers.
fleXo high performAnCe progrAmm ABle CloCkS
FleXO is the industry’s most flexible family of ultra low-jitter clock generators, ideal for networking equipment and other high-performance
applications. The FleXO family exceeds the clock requirements for demanding high-speed serial interface standards such as 10 Gigabit
Ethernet, 10 Gigabit Fibre Channel, SAS/SATA, and PCI Express.
FleXO clock generators can be instantly programmed in the factory or field to frequencies up to 690 MHz, enabling designers to optimize
system performance and use a single device across a family of platforms. A key FleXO feature, frequency margining, enables designers
to vary clock frequency with 0.2 ppm precision to test system robustness across potential frequency fluctuations during both design and
production stages.

Programmable timing solutions combine the convenience of field programming with the customary high performance of Cypress’s timing
products. Use CyberClocks
™
Online Software to optimize device parameters.
View software and drivers online at
www.cypress.com/go/clocksoftware.
Each programmed device can be optimized for a specific
board layout.
In-System Programmable (ISP) Clocks, also known as In-System Reprogrammable (ISR) Clocks, are customizable at any point in the lifetime
of the product. A customized clock configuration can be programmed through the I
2
C interface to enable one part number to be ordered,
stocked, and placed on different boards, then customized with the specific frequencies as required.

FailSafe
™
devices provide an optimum solution for applications where continuous operation is required in the event of a primary clock failure.
Continuous operation is achieved using a DCXO that serves as a redundant clock source, maintaining the last frequency and phase infor-
mation of the reference clock.
The Field Programmable Zero Delay Buffer is a high-performance clock distribution device that can be customized for a wide range of
applications. The device is implemented on Cypress’s proprietary non-volatile technology. It is fully programmable via volume or prototype
programmers. The device enables the user to define an Application Specific clock distribution device with customized input and output
dividers, feedback topology (internal/external), output inversions and output drive strengths.
