1.5 Specified Electrical Performance with 15 mm Interconnect and Zarlink ZLE40510/14
Evaluation Board
The specified performance in the table are results based on the electrical measurements and simulations across
full process corners using the Zarlink Evaluation Board using a 3.9 Ohm resistive load to ground.
The track interconnect between ZL40510/14 and the 3.9 Ohm Resistor is 15 mm long and uses a 2 mm wide track
on single sided FR4 board. The return path is via two 2 mm wide tracks spaced 0.25 mm either side of the track
between output and the 3.9 Ohm resistor. The combined forward and return path forms a co planar transmission
line with a characteristic impedance of approximately 120 Ohms.
The tight coupled return paths carrying the return current reduce the effective series inductance (Leff) which can be
approximated to:
Leff = 2 * Lint * (1 - K) + 2 * Lfix * (1 - K).
The ZLE40510 board has two positions for the Laser Diode at two different distances. (15 and 30 mm).
The measured value of Leff is 7 nH
The estimated value of Leff = 2 * 8 (1 – 0.5) = 8 nH
The actual pulse response achieved in an application is thus dependent on the application.
1.6 Application Layout Guide Lines
Minimize interconnect inductance by:
a. Using Short Interconnect Distance
b. Use wide interconnect tracks
c. Keep the return path tightly coupled to the forward path.
