FEATURES
PRODUCT DESCRIPTION
PhaseLink’s Analog Frequency Multiplier TM (AFMs)
are the industry’s first ‘Balanced Oscillator’ utilizing
analog multiplication of the fundamental frequency
(at double or quadruple frequency), combined with
an attenuation of the fundamental of the reference
crystal, without the use of a phase locked loop, in
CMOS technology.
PhaseLink’s patent pending PL56X family of AFM
products can achieve up to 800 MHz output
frequency with practically no jitter or phase noise
deterioration. In addition, the low frequency input
crystal requirement makes the AFMs the most
affordable high performance timing source in the
market.
PL560-XX family of products utilize a low-power
CMOS technology and are housed in a 16-pin
(T)SSOP, and 16-pin 3x3 QFN.

To minimize parasitic effects, and improve performance:
• Place the crystal as close as possible to the IC.
• Make the board traces that are connected to the crystal pins symmetrical.
• The board trace symmetry is important, as it reduces the negative parasitic effects, for a clean frequency multiplication with low
jitter. Parasitic have negative effect on frequency pulling of a VCXO and jitter.

EXTERNAL COMPONENT VALUES
INDUCTOR VALUE OPTIMIZATION
The required inductor value(s) for the best performance depends on the operating frequency, and the board
layout specifications. The listed values in this datasheet are based on the calculated parasitic values from
PhaseLink’s evaluation board design (Gerber file available upon request). These inductor values provide the user
with a starting point to determine the optimum inductor values. Additional fine-tuning may be required to
determine the optimal solution.
To assist with the inductor value optimization, PhaseLink has developed the “AFM Tuning Assistant” software.
You can download this software from PhaseLink’s web site (www.phaselink.com). The software consists of two
worksheets. The first worksheet (named L2) is used to fine-tune the ‘L2’ inductor value, and the second
worksheet (named L4) is used for fine tuning of the ‘L4’ (used in 4x AFMs only) inductor value.
For those designs using PhaseLink’s recommended board layout, you can use the “AFM Tuning Assistant” to
determine the optimum values for the required inductors. This software is developed based on the parasitic
information from PhaseLink’s board layout and can be used to determine the required inductor and parallel
capacitor (see LWB1 and Cstray parameters) values. For those employing a different board layout in their
design, we recommend to use the parasitic information of their board layout to calculate the optimized inductor
values. Please use the following fine tuning procedure:

- C11 = 0.4 pF, The following amplifier stage

- LWB1 = 2 nH, (2 places), Stray inductance
- Cstray = 1.0 pF, Stray Capacitance
- L2X (L4X) = 2x or 4x inductor
- C2X (C4X) = range (0.1 to 2.7), Fine tune
inductor if used
• There are two default variables that normally will not need to be modified. These are Cpad, and C11 and
are found in cells B22 and B27 of ‘AFM Tuning Assistant’, respectively.
• LWB1 is the combined stray inductance in the layout. The DIE wire bond is ~ 0.6 nH and in the case of a
leaded part an additional 1.0 nH is added. Your layout inductance must be added to these. There are 2 of
these and they are assumed to be approximately symmetrical so you only need to enter this inductance
once in cell B23.
• Enter the stray parasitic capacitance into cell B26. An additional 0.5 pF must be added to this value if a
leaded part is used.
• Enter the appropriate value for Cinternal into B21 based on the device used (see column D). Use the ‘AFM
Tuning Assistant’ software to calculate L2X (and C2X if used) for your resonance frequency.
• For 4X AFMs, repeat the same procedure in the L4X worksheet.
• See the examples below.

DETERMINING STRAY L’s AND C’s IN A LAYOUT
Figure 5: Diagram Representation of the Board Layout
Lets take the PL560-38 (4x VCXO) for example. This takes a crystal input range of 30 to 80 MHz and multiplies
this to an output of 120 to 320 MHz. To determine the stray L’s and C’s of the layout we will assemble two test
units. One AFM will be tuned to the lower range of the device (120 MHz), and the other to the upper range of the
device (320 MHz).
120 MHz AFM Tuning: Using the “AFM Tuning Assistant” find the PL560-3x in the L2x worksheet. Enter the
Cinternal value found next to it into cell B21. In cell B24 enter the closest standard inductor value (see CoilCraft
0603CS series for example) to achieve the closest peak frequency to 60 MHz. Repeat the same procedure for
L4x at 120 MHz.
Results: L2X = 180 nH, L4X = 82 nH.
320 MHz AFM tuning: Repeat the previous procedure for L2x at 120 MHz and L4x at 320 MHz.
Results: L2X = 24 nH, L4X = 10 nH.
Proceed and assemble the test units.
Measuring 120 MHz L2x: Connect the RF generator and scope probe as shown in Figure 6, above. While
power is applied to the PCB, set the generator output to +12 dBm and the frequency to 30 MHz. Since this is the
2x port, the scope will show 60 MHz with ~ 3v pk-pk amplitude. Vary the generator above and below 30 MHz until
the amplitude on the scope is maximum and record the generator frequency. For example peak accorded at
29.8x2 or 59.6 MHz.

Measuring 320 MHz L2x: Connect the RF generator and scope probe as shown in Figure 6, above. While
power is applied to the PCB, set the generator output to +12 dBm and the frequency to 80 MHz. Since this is the
2x port the scope will show 160 MHz with ~ 3v pk-pk amplitude. Vary the generator above and below 80 MHz
until the amplitude on the scope is maximum and record the generator frequency. For example peak accorded at
78.0 x 2 = 156 MHz
In the AFM Tuning Assistant, add the scope’s probe capacitance to the Cstray cell. For our example 0.5 pF + 1.0
pF = 1.5 pF. With L2X at 24 nH adjust LWB1 (cell B23) until the peak frequency reads 156 MHz. Next replace the
L2x value with 180 nH and see if it peaks at 59.6 MHz. IF it it does not, adjust the Cstray until 59.4 MHz is
achieved. Again enter 24 nH for L2x and fine tune LWB1 for 156 MHz.
Results: LWB1 = 1.6 nH, Cstray = 2.9 pF-0.5 pF = 2.4 pF (subtract scope probe stray)
Repeat the same steps for the L4X: Set the generator to 80 MHz. The 82 nH peaks at 118 MHz and the 10 nH
peaks at 304 MHz.
Results: LWB1 = 1.8 nH, Cstray = 2.5 pF-0.5 pF = 2.0 pF (subtract scope probe stray)

BOARD LAYOUT DESIGN CONSIDERATIONS FOR AFMs
L2x and L4x: Try to reduce the PCB trace
inductance to a minimum by placing L2x and L4x as
physically close to their respective pins as possible.
Also be sure to bypass each Vdd connection
especially taking care to place a 0.01 uF bypass at
the Vdd side of L2x and L4x (See recommended
layout).
Note: Please contact PhaseLink for the Gerber
files of the board layouts.
Crystal connections: Be sure to keep the ground
plane under the crystal connections continuous so
that the stray capacitace is consistent on both
crystal connections. Also be sure to keep the crystal
connections symmetrical with respect to one another
and the crystal connection pins of the IC. If you
chose to use a series capacitance and or inductor to
fine tune the crystal frequency be sure to put
symmetrical pads for this cap on both crystal pins
(see Cadj in recommended layout). Even if one of
the capacitors with be a 0.01 uf and the other is
used to tune the frequency. And to further maintain
a symmetrical balance on a crystal that may have
more internal Cstray on one pin or the other. Place
capacitor pads (Cbal) on each crystal lead to ground
(see recommended layout). You can refer to (xxx) if
tuning of Cbal is required. R3rd is only required if a
3 rd overtone crystal is used.
4X Layout
Vdd and Gnd: Bypass VDDANA and VDDBUF with
separate bypass capacitors and if a Vdd plane is
used feel each bypass cap with its own via. And be
sure to connect any ground pin including the bypass
caps with short via connection to the ground plane.
OESEL: J1 is recommended so the same PCB
layout can be used for both Output Enable low (No
J1) or Output Enable high (J1 = ohms) if this
function is chosen.

Description
Do Not Connect.
External inductor connection. The inductor is recommended to be a high Q small
size 0402 or 0603 SMD component, and must be placed between L4X and adjacent
VDDOSC. Place inductor as close to the IC as possible to minimize parasitic effects
and to maintain inductor Q. This inductor is used with 4X AFMs.
2X
GND connection.

VDD connection for oscillator circuitry. VDDOSC should be separately decoupled from other
