Benefits
Provides a wide range of spread percentages for maximum
electromagnetic interference (EMI) reduction to meet
regulatory agency electromagnetic compliance (EMC) require-
ments. Reduces development and manufacturing costs and
time-to-market.
This versatile programming feature enables the user to switch
between SSXO (with Spread) and XO (without Spread)
functions with ease.
Internal PLL to generate up to 166 MHz output.
Suitable for most PC, consumer, and networking applications
Application compatibility in standard and low power systems
In house programming of samples and prototype quantities is
available using CY3672 programming kit and CY3724 socket
adapters. Production quantities are available through
Cypress’s value added distribution partners or by using third
party programmers from BP Microsystems, and HiLo Systems,
and others.
