PCB Layout Recommendations
Printed circuit board layout affects the performance of the
CLC005. The following guidelines will aid in achieving satis-
factory device performance.
• Use a ground plane or power/ground plane sandwich de-
• Bypass device power with a 0.01 µF monolithic ceramic
• Provide short, symmetrical ground return paths for:
• Provide short, grounded guard traces located
— inputs,
— supply bypass capacitors and
— the output load.
— under the centerline of the package,
— 0.1 (2.5 mm) from the package pins
— on both top and bottom of the board with connecting
sign for optimum performance.

pacitor located no more than 0.1 (2.5 mm) from the de-
vice power pins.

EVALUATION BOARD
A schematic, parts list and layout for a suitable evaluation
board are given on the following page. The artwork includes
trace, silk screen and ground layers. The individual printed
circuit board is available unassembled from National Semi-
conductor. To order this evaluation board, part number
CLC730056, contact your local sales representative or
the National Semiconductor Customer Response Center
in your area. (This evaluation board is identical to that for
the CLC007 for which some of the listed parts are not re-
quired.)
The evaluation board is a guide to proper circuit layout and
makes prototyping and measurement-taking easy. Since the
board is designed to accommodate many of the application
circuits possible with the CLC005, your particular application
may not require all of the listed parts or may require different
values. The evaluation board may be powered from standard
ECL supply voltages by installing the two jumpers in the lo-
cations labeled “−5”. For PECL supply voltages, install the
jumpers in the locations labeled “+5”.
