Functional Description
The FS0 and FS1 pins select between four different output
frequencies, as shown in
common application for this feature. One frequency is used for
the standard operating mode of the device, while the other
frequencies are available for margin testing, either during
product development or in system manufacturing test.
Table 2. Frequency Select
When changing the output frequency, the frequency transition is
not guaranteed to be smooth. There can be frequency
excursions beyond the start frequency and the new frequency.
Glitches and runt pulses are possible, and time must be allowed
for the PLL to relock.
Programming Description
The CY2XF33 is a programmable device. Before being used in
an application, it must be programmed with the output
frequencies and other variables described in a later section. Two
different device types are available, each with its own
programming flow. They are described in the following sections.

Field Programmable CY2XF33F
Field programmable devices are shipped unprogrammed and
must be programmed before being installed on a printed circuit
board (PCB). Customers use CyberClocks™ Online Software to
specify the device configuration and generate a JEDEC
(extension .jed) programming file. Programming of samples and
prototype quantities is available using a Cypress programmer.
Third party vendors manufacture programmers for small to large
volume applications. Cypress’s value added distribution partners
also provide programming services. Field programmable
devices are designated with an “F” in the part number. They are
intended for quick prototyping and inventory reduction. The
CY2XF33 is one time programmable (OTP).
The software is located at www.cyberclocksonline.com.
Factory Configured CY2XF33
For customers wanting ready-to-use devices, the CY2XF33 is
available with no field programming required. All requests are
submitted to the local Cypress Field Application Engineer (FAE)
or sales representative. After the request is processed, the user
receives a new part number, samples, and data sheet with the
programmed values. This part number is used for additional
sample requests and production orders.
