CY22050
Programming Description
Applications
Field Programming the CY22050F
Controlling Jitter
The CY22050 is programmed at the package level, that is, in a
programmer socket, prior to installation on a PCB. The CY22050
is flash-technology based, so the parts can be reprogrammed up
to 100 times. This allows for fast and easy design changes and
product updates, and eliminates any issues with old and
out-of-date inventory.
Jitter is defined in many ways, including: phase noise, long-term
jitter, cycle-to-cycle jitter, period jitter, absolute jitter, and
deterministic jitter. These jitter terms are usually given in terms
of rms, peak-to-peak, or in the case of phase noise dBC/Hz with
respect to the fundamental frequency. Actual jitter is dependent
on XIN jitter and edge rate, number of active outputs, output
frequencies, VDDL (2.5 V or 3.3 V), temperature, and output load.
Samples and small prototype quantities can be programmed on
the CY3672 programmer. Cypress’s value-added distribution
partners and third-party programming systems from BP
Microsystems, HiLo Systems, and others are available for
large-production quantities.
CyberClocks Software
CyberClocks is an easy-to-use software application that allows
the user to custom-configure the CY22050. Within CyberClocks,
select the CyClocksRT tool. Users can specify the REF, PLL
frequency, output frequencies and/or post-dividers, and different
functional options. CyClocksRT outputs an industry-standard
JEDEC file used for programming the CY22050.
CyClocksRT can be downloaded free of charge from the
Cypress website at http://www.cypress.com. Install and run it on
any PC running the Windows operating system.
CY3672 Development Kit
The Cypress CY3672 Development Kit comes complete with
everything needed to design with the CY22050 and program
samples and small prototype quantities. The kit comes with the
latest version of CyClocksRT and a small portable programmer
that connects to a PC for on-the-fly programming of custom
frequencies.
The JEDEC file output of CyClocksRT can be downloaded to the
portable programmer for small-volume programming, or for use
with a production programming system for larger volumes.
Document Number: 38-07006 Rev. *O
Power supply noise and clock output loading are two major
system sources of clock jitter. Power supply noise can be
mitigated by proper power supply decoupling (0.1-F ceramic
cap) of the clock and ensuring a low-impedance ground to the
chip. Reducing capacitive clock output loading to a minimum
lowers current spikes on the clock edges and thus reduces jitter.
Reducing the total number of active outputs also reduce jitter in
a linear fashion. However, it is better to use two outputs to drive
two loads than one output to drive two loads.
The rate and magnitude that the PLL corrects the VCO frequency
is directly related to jitter performance. If the rate is too slow, then
long term jitter and phase noise is poor. Therefore, to improve
long-term jitter and phase noise, reducing Q to a minimum is
advisable. This technique increases the speed of the phase
frequency detector, which in turn drives the input voltage of the
VCO. In a similar manner, increasing P until the VCO is near its
maximum rated speed also decreases long term jitter and phase
noise. For example: input reference of 12 MHz; desired output
frequency of 33.3 MHz. One might arrive at the following
solution: Set Q = 3, P = 25, Post Div = 3. However, the best jitter
results are Q = 2, P = 50, Post Div = 9.
For additional information, refer to the application note, “Jitter in
PLL-based Systems: Causes, Effects, and Solutions,” available
at http://www.cypress.com (click on “Application Notes”), or

CY22050
CY22050 Frequency Calculation
The CY22050 is an extremely flexible clock generator with up to
six individual outputs, generated from an integrated PLL.
There are four variables used to determine the final output
frequency. They are: the input REF, the P and Q dividers, and
the post divider. The three basic formulas for determining the
final output frequency of a CY22150-based design are:
■
CLK = ((REF * P)/Q)/Post Divider
■
CLK = REF/Post Divider
■
CLK = REF
The basic PLL block diagram is shown in Figure 2. Each of the
six clock outputs has a total of seven output options available to
it. There are six post divider options: /2 (two of these), /3, /4,
/DIV1N, and DIV2N. DIV1N and DIV2N are separately calculated
and can be independent of each other. The post divider options
can be applied to the calculated PLL frequency or to the REF
directly.
In addition to the six post divider options, the seventh option
bypasses the PLL and passes the REF directly to the crosspoint
switch matrix.

Each of the six clock outputs can come from any of seven unique

source is attached to each individual clock output. Although it
may seem that there are an unlimited number of divider options,
there are several rules that must be taken into account when
selecting divider options.

Definition and Notes
Clock output source is the reference input frequency.
/DIV1N
Clock output uses a generated /DIV1N option from Divider Bank 1. Allowable values for DIV1N are 4 to
130. If Divider Bank 1 is not being used, set DIV1N to 8.
/2
Clock output uses a fixed /2 option from Divider Bank 1. If this option is used, DIV1N must be divisible by 4.
/3
Clock output uses a fixed /3 option from Divider Bank 1. If this option is used, set DIV1N to 6.
/DIV2N
Clock output uses a generated /DIV2N option from Divider Bank 2. Allowable values for DIV2N are 4 to
130. If Divider Bank 2 is not being used, set DIV2N to 8.
/2
Clock output uses a fixed /2 option from Divider Bank 2. If this option is used, DIV2N must be divisible by 4.
/4
Clock output 2 uses a fixed /4 option from Divider Bank 2. If this option is used, DIV2N must be divisible by 8.

CY22050
Reference Crystal Input
The input crystal oscillator of the CY22050 is an important
feature because of the flexibility it allows the user in selecting a
crystal as a reference clock source. The oscillator inverter has
programmable gain, allowing for maximum compatibility with a
reference crystal, based on manufacturer, process,
performance, and quality.
The value of the input load capacitors is determined by eight bits
in a programmable register. Total load capacitance is determined
by the formula:
CapLoad = (CL – CBRD – CCHIP)/0.09375 pF
In CyClocksRT, enter the crystal capacitance (CL). The value of
CapLoad is determined automatically and programmed into the
CY22050.
If you require greater control over the CapLoad value, consider
using the CY22150 for serial configuration and control of the
input load capacitors. For an external clock source, the default is
0.
Input load capacitors are placed on the CY22050 die to reduce
external component cost. These capacitors are true
parallel-plate capacitors, designed to reduce the frequency shift
that occurs when non-linear load capacitance is affected by load,
bias, supply, and temperature changes.
Crystal Drive Level and Power
Crystals are specified to accept a maximum drive level.
Generally, larger crystals can accept more power. The drive level
specification in the table below is a general upper bound for the
power driven by the oscillator circuit in the CY22050.
For a given voltage swing, power dissipation in the crystal is
proportional to ESR and proportional to the square of the crystal
frequency. (Note that actual ESR is sometimes much less than
the value specified by the crystal manufacturer.) Power is also
almost proportional to the square of CL.
Power can be reduced to less than the DL specification in the
table below by selecting a reduced frequency crystal with low CL
and low R1 (ESR).

loaded with 15 pF.
6. Use CyClocksRT to calculate actual IVDD and IVDDL for specific output frequency configurations.
7. Skew value guaranteed when outputs are generated from the same divider bank. See Logic Block Diagram for more information.
8. Jitter measurement will vary. Actual jitter is dependent on XIN jitter and edge rate, number of active outputs, output frequencies, VDDL (2.5 V or 3.3 V), temperature,
