VCXO-TO-6 LVCMOS OUTPUTS
GENERAL DESCRIPTION
FEATURES
The ICS81006 is a high performance, low • Six LVCMOS/LVTTL outputs, 20Ω nominal
ICS
jitter/low phase noise VCXO and is a
member of the HiPerClockS™ family of high
performance clock solutions from ICS. The
ICS81006 works in conjunction with a
output impedance
HiPerClockS™
• Output Q5 can be selected for ÷1 or ÷2 frequency relative
to the crystal frequency
pullable crystal to generate an output clock over the
range of 12MHz - 40MHz and has 6 LVCMOS outputs,
effectively integrating a fanout buffer function.
• Output frequency range: 12MHz to 40MHz
• Crystal pull range:
ꢀ0ppm ꢁtypicalꢂ
• Synchronous output enable places outputs in High-Z state
• On-chip filter onVIN to suppress noise modulation of VCXO
• VDD/VDDO combinations
The frequency of the VCXO is adjusted by the VC control
voltage input. The output range is 100ppm around the
nominal crystal frequency. The VC control voltage range
is 0 - VDD. The device is packaged in a small 4mm x 4mm
VFQFN package and is ideal for use on space
constrained boards typically encountered in ADSL/
VDSL applications.

2.5V/1.8V
• 4mm x 4mm 20 Lead VFQFN package is ideal for space
constrained designs
• 0°C to 70°C ambient operating temperature
• Available in both standard and lead-free RoHS compliant
packages

the inaccuracy due to aging is 15ppm. Third, though many
boards will not require load tuning capacitors ꢁCL1, CL2ꢂ, it is
recommended for long-term consistent performance of the
system that two tuning capacitor pads be placed into every
design.Typical values for the load tuning capacitors will range
from 0 to 4pF.
Using the tables and figures above, we can now calculate the
TPR and APR of the VCXO using the example crystal
parameters. For the numerical example below there were some
assumptions made. First, the stray capacitance ꢁCS1, CS2ꢂ, which
is all the excess capacitance due to board parasitic, is 4pF.
Second, the expected lifetime of the project is 5 years; hence

TPR = 113.25ppm

The example above will ensure a total pull range of with better pullability ꢁC0/C1 ratioꢂ can be used. Also, with the
113.25 ppm with an APR of 58.25ppm. Many times, board equations above, one can vary the frequency tolerance,
designers may select their own crystal based on their temperature stability, and aging or shunt capacitance to achieve
application. If the application requires a tighter APR, a crystal the required pullability.
