These guidelines ensure the most reliable PLR152 POF performance for the motherboard integration. Failed to implement these PCB guidelines may affect the PLR152 jitter and low input power performances. 1. Careful decoupling of the power supplies is very important. Place a 0.47uf surface mount (size 805 or smaller) capacitor as close as (less than 2cm) to the POF Vdd and Gnd leads. The 0.47uf 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 EVERLIGHT ELECTRONICS CO., LTD.
