PCB LAYOUT RECOMMENDATIONS
Printed circuit board layout affects the performance of the
CLC016. The following are PCB layout rules for the CLC016:
1.
Use a ground plane.
2.
De-couple V
/V
EE
power pins with 0.01 μF ceramic ca-
pacitors placed
≤
6.8 μF tantalum capacitors.
3.
For long signal runs, match transmission lines to the de-
sired characteristic impedance for the input and output
lines.
4.
Remove ground plane 0.025” (0.06mm) from all pads.
5.
Remove ground plane from the area around the loop fil-
ter and frequency selection resistors.
6.
Keep digital and analog lines sufficiently away from loop
filter or frequency selection resistors.
7.
Avoid the use of sockets in production boards.
8.
In proto-boards use a low-profile, low impedance, type
socket.
EVALUATION BOARD
An evaluation board layout and schematic are shown on the
following page. The art work shows the board solder masks,
trace layers, and ground plane.
To order an evaluation
board, contact your local sales representative or Na-
tional
support
center
and
CLC730057.
The evaluation board provides LEDs and switches to oper-
ate the PLL in various modes. The board allows the user to
select +5V or 5.2V power supplies, identified on the printed
board silk screen. Insert all tantalum capacitors as shown in
the schematic or silk screen. A complete bill of materials is
given in the following table. The components recommended
in the materials list are for SMPTE 259M standards.
