■ Differential low-voltage positive emitter coupled logic
(LVPECL) output
■ Output frequency from 50 MHz to 690 MHz
■ Frequency margining through I
2
C bus
■ Factory-configured or field-programmable
■ Integrated phase-locked loop (PLL)
■ Pb-free package: 5.0 × 3.2 mm leadless chip carrier (LCC)
■ Supply voltage: 3.3 V or 2.5 V
■ Commercial and industrial temperature ranges
Functional Description
The CY2XF24 is a high-performance and high-frequency XO. It
uses a Cypress-proprietary low-noise PLL to synthesize the
frequency from an integrated crystal. The output frequency can
be changed using the I
2
C bus serial interface, allowing easy
frequency margin testing in applications.
The CY2XF24 is available as a factory-configured device or as
a field-programmable device. Factory-configured devices are
configured for general use (see Standard and Appli-
cation-Specific Factory Configurations) or they can be customer
specific.
