The PL610 is a high performance general purpose
oscillator IC for outputs up to 130MHz. Designed to
fit in a small 2 x 1.3mm DFN or 3 x 3mm SOT23
package, the PL610 offers the best phase noise and
jitter performance and lowest power consumption of
any comparable IC.
In addition, there is a ‘6’ bit optional programmable
Odd/Even divider (default= ٪1), and ‘3’
programmable output drive strengths (4mA, 8mA
(default), 16mA) to choose from. The full feature set
of the PL610 makes it the most versatile XO for any
application.

1.8V to 3.3V, 1MHz to 130MHz XO IC
FUNCTIONAL DESCRIPTION
PL610-01 is a highly featured, very flexible, advanced XO design for high performance, low-power, small formfactor applications. The PL610-01 accepts a fundamental input crystal of 5MHz to 130MHz or a reference clock
input of 1MHz to 130MHz and is capable of producing two outputs up to 130MHz. This flexible design allows the
PL610-01 to deliver any frequency, FREF (Crystal or Ref Clk) frequency, FREF / 2 or FREF / P to CLK0 and/or
CLK1. Some of the design features of the PL610-01 are mentioned below:
Clock Output (CLK0)
Power-Down Control (PDB)
CLK0 is the main clock output. The output from CLK0
can be FREF (Crystal or Ref Clk), FREF/2 or FREF/P
output. The output drive level can be programmed to
Low Drive (4mA), Standard Drive (8mA) or High Drive
(16mA).
The Power Down (PDB) feature allows the user to
put the PL610-01 into “Sleep Mode”. When
activated (logic ‘0’), PDB ‘Disables the PLL, the
oscillator circuitry, counters, and all other active
circuitry. In Power Down mode the IC consumes
<10µA of power. The PDB pin incorporates a 10MΩ
pull up resistor giving a default condition of logic “1”.
Programmable I/O (OE/PDB/CLK1)
The PL610-01provides one programmable I/O pin
which can be configured as one of the following
functions:
Output Enable (OE)
The Output Enable feature allows the user to enable
and disable the clock output(s) by toggling the OE
pin. The OE pin incorporates a 60kΩ pull up
resistor giving a default condition of logic “1”.
Clock Output (CLK1)
The CLK1 feature allows the PL610-01 to have an
additional clock output programmed to one of the
following:
FREF - Reference (Crystal or Ref Clk)
Frequency
FREF / 2
CLK0

LAYOUT RECOMMENDATIONS
The following guidelines are to assist you with a performance optimized PCB design:
Signal Integrity and Termination
Considerations
Decoupling and Power Supply
Considerations
- Keep traces short!
- Place decoupling capacitors as close as possible to
the VDD pin(s) to limit noise from the power supply
- Trace = Inductor. With a capacitive load this equals
ringing!
- Long trace = Transmission Line. Without proper
termination this will cause reflections (looks like ringing).
- Design long traces as “striplines” or “microstrips” with
defined impedance.
- Match trace at one side to avoid reflections bouncing
back and forth.
- Multiple VDD pins should be decoupled separately
for best performance.
- Addition of a ferrite bead in series with VDD can
help prevent noise from other board sources
- Value of decoupling capacitor is frequency
dependant. Typical values to use are 0.1F for
designs using crystals < 50MHz and 0.01F for
designs using crystals > 50MHz.
( Typical buffer impedance 20

Use value to match output
buffer impedance to 50
