EVERLIGHT ELECTRONICS CO., LTD. http://www.everlight.c om Rev 1 Page: 8 of 8 Device NO: DPL-253-001 Prepared Date:05-15-2006 Prepared By: Chin-Chia Hsu PLR253 Series To achieve better jitter and low input optical power performances, several PCB layout guidelines must be followed. These guidelines en sure the most reliable PLR253 POF performance for the motherboard integration. Failed to implement these PCB guidelines may affect the PLR253 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 digita l IC on the motherboard, the planar capacitance formed by an isolated Vcc and Gnd planes is cr itical. 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 connect ed to the main Vcc and Gnd (digital) planes at a single point using ferrite beads. The beads ar e used to block the high frequency noises from the digital planes while still allowing the DC connections between the planes EVERLIGHT ELECTRONICS CO., LTD.
