Zarlink Semiconductor Inc.
Specified Electrical Performance with 15 mm Interconnect and Zarlink ZLE40539 Evaluation Board
The specified transient pulse 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 ZL40539 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 ZLE40539 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.
Application Layout Guide Lines
Minimize Interconnect Inductance by:
1. Using Short Interconnect Distance
2. Use wide interconnect tracks
3. Keep the return path tightly coupled to the forward path
