Application Notes: PLR135 Series PCB layout for motherboard integration

To achieve better jitter and low input optical power performances, several PCB layout guidelines must be followed.

These guidelines ensure the most reliable PLR135 POF performance for the motherboard integration. Failed to implement

these PCB guidelines may affect the PLR135 jitter and low input power performances.

1. Careful decoupling of the power supplies is very important. Place a 0.1uf surface mount (size 805 or smaller)

capacitor as close as (less than 2cm) to the POF Vdd and Gnd leads. The 0.1uf act as a low impedance path to

ground for any stray high frequency transient noises.

2. To reduce the digital noises form the digital IC on the motherboard, the planar capacitance formed by an isolated Vcc

and Gnd planes is critical. The POF device must be mounted directly on these two planes to reduce the lead parasitic

inductance.

3. The isolated Vdd and Gnd planes must be connected to the main Vcc and Gnd (digital) planes at a single point using

ferrite beads. The beads are used to block the high frequency noises from the digital planes while still allowing the DC

connections between the planes
