Programming Description

The CY2X013 is a programmable device. Prior to being used in

an application, it must be programmed with the output frequency

and other variables described in Programming Variables. Two

different device types are available, each with its own

programming flow. They are described in the following sections.

Field Programmable CY2X013F

Field programmable devices are shipped unprogrammed and

must be programmed before being installed on a PCB.

Customers use CyClockWizard™ software to specify the device

configuration and generate a joint electron devices engineering

file.

Programming of samples and prototype quantities is available

using

the

CyClockWizard

software

along

with

a

CY3675-CLKMAKER1 CyClockMaker Clock Programmer Kit

with a CY3675-LCC6A socket adapter. 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.

paragraph.

Factory Configured CY2X013

For ready-to-use devices, the CY2X013 is available with no field

programming required. Pre-configured devices (see Standard

and Application-Specific Factory Configurations) are available

for samples or orders, or a request for a custom configuration

can be made. 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 datasheet with the programmed values. This part

number is used for additional sample requests and production

orders. The CY2X013 is one-time programmable (OTP).

Programming Variables

Output Frequency

The CY2X013 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 CY2X013 has an output frequency range of 50 MHz to

690 MHz, but the range is not continuous. The CY2X013 cannot

generate frequencies in the ranges of 521 MHz to 529 MHz and

596 MHz to 617 MHz.

Pin 1: Output Enable (OE) or Power-Down (PD#)

Pin 1 is programmed as either OE or 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 the lock.

Industrial versus 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. CyClockWIzard software allows the user to select

between and view the expected performance of both options.
