NOTES:
1. PLACE TERMINATION RESISTORS NEAR INPUT DATA PINS OF TRANSCEIVER AND PHY DEVICES.
2. MAKE DIFFERENTIAL SIGNAL PATHS SHORT AND OF THE SAME LENGTH WITH EQUAL TERMINATIONS TO VCC – 2 VOLTS.
3. SIGNAL TRACES SHOULD BE 50 Ω TRANSMISSION LINES: MICROSTRIP (OR STRIPLINE). USE GROUND PLANE
(OR MULTI-LAYER) PRINTED CIRCUIT BOARD FOR BEST HIGH FREQUENCY PERFORMANCE.
4. RESISTORS IN Ω. CAPACITORS IN MICROFARADS. INDUCTORS IN MICROHENRIES.
5. USE HIGH-FREQUENCY MONOLITHIC CERAMIC BYPASS CAPACITORS AND LOW SERIES DC RESISTANCE INDUCTORS.
FERRITE INDUCTORS CAN BE USED.
LOCATE POWER SUPPLY FILTER COMPONENTS CLOSE TO FIBER-OPTIC DEVICES.
6. CAUTION: DO NOT DIRECTLY CONNECT FIBER-OPTIC MODULE PECL OUTPUTS (DATA, DATA, SIGNAL DETECT, SIGNAL DETECT)
TO GROUND WITHOUT PROPER CURRENT LIMITING IMPEDANCE.
7. DEVICE GROUND PINS SHOULD BE DIRECTLY AND INDIVIDUALLY CONNECTED TO GROUND.
8. DEVICE SOLDER POSTS SHOULD BE DIRECTLY CONNECTED TO PCB FOR OPTIMUM MECHANICAL SUPPORT.
