Programming Description
The CY2X014 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 CY2X014F
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 software is located at www.cyberclocksonline.com.
Factory Configured CY2X014
For ready-to-use devices, the CY2X014 is available with no field
programming required. All requests are submitted to the local
Cypress Field Application Engineer (FAE) or sales represen-
tative. After the request is processed, you receive a new part
number, samples, and datasheet with the programmed values.
This part number is used for additional sample requests and
production orders. The CY2X014 is One Time Programmable
(OTP).
Programming Variables
Output Frequency
The CY2X014 can synthesize a frequency to a resolution of one
part per million (ppm), but the actual accuracy of the output
frequency is limited by the accuracy of the integrated reference
crystal.
The CY2X014 has an output frequency range of 50 MHz to 690
MHz, but the range is not continuous. The CY2X014 cannot
generate frequencies in the ranges of 521 MHz to 529 MHz and
596 MHz to 617 MHz.

I/O Type
Output Enable Pin: Active HIGH. If OE = 1, CLK is enabled.
Power Down Pin: Active LOW. If PD# = 0, the device is powered down and the clock is
disabled. The functionality of this pin is programmable.
Do Not Use: DNU pins are electrically connected, but perform no function
Supply Voltage: 2.5V or 3.3V
Ground
Pin 1: Output Enable or Power Down (OE/PD#)
Pin 1 is programmed as either Output Enable (OE) or Power
Down (PD#). The OE function is used to enable or disable the
CLK output quickly, but it does not reduce core power
consumption. The PD# function puts the device into a low power
state, but the wake up takes longer because the PLL must
reacquire lock.
Industrial vs. Commercial Device Performance
Industrial and Commercial devices have different internal
crystals. They have a potentially significant impact on
performance levels for applications requiring the lowest possible
phase noise. CyberClocks Online Software displays expected
performance for both options.
Phase Noise vs. Jitter Performance
In most cases, the device configuration for optimal phase noise
performance is different from the device configuration for optimal
cycle to cycle or period jitter. CyberClocks Online Software
includes algorithms to optimize performance for either
parameter.
