They are not meant to imply that the devices should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation. Note 2:Min/max ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality levels are determined from tested parameters. Note 3:Spec is 100% tested at +25˚C, sampled tested at +85˚C. Note 4:Spec is 100% tested at +35˚C at wafer probe. Note 5:Spec is guaranteed by design. Note 6:Measured between the 20% and 80% levels of the waveform. Note 7:Measured with both outputs driving 150Ω , AC coupled at 270 Mbps. www.national.com 2

PCB Layout Recommendations Printed circuit board layout affects the performance of the CLC007. The following guidelines will aid in achieving satis- factory device performance.

  • Use a ground plane or power/ground plane sandwich de- sign for optimum performance.
  • Bypass device power with a 0.01 µF monolithic ceramic capacitor in parallel with a 6.8 µF tantalum electrolytic ca- pacitor located no more than 0.1″ (2.5 mm) from the de- vice power pins.
  • Provide short, symmetrical ground return paths for: — inputs, — supply bypass capacitors and — the output load.
  • Provide short, grounded guard traces located — 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 vias. 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 CLC006 the use for which may require additional parts.) 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 CLC007, 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”. DS100085-12 CLC007 Evaluation Board Schematic www.national.com7
