Figure 2 - Recommended Gigabit/sec Ethernet HFBR-5911LZ/ALZ Fiber-Optic Transceiver and HDMP-1687 SERDES Integrated Circuit Transceiver
Interface and Power Supply Filter Circuits.
NOTES:
USE SURFACE-MOUNT COMPONENTS FOR OPTIMUM HIGH-FREQUENCY PERFORMANCE.
USE 50 W MICROSTRIP OR STRIPLINE FOR SIGNAL PATHS.
LOCATE 50 W TERMINATIONS AT THE INPUTS OF RECEIVING UNITS.
*C8 IS A RECOMMENDED BYPASS CAPACITOR FOR ADDITIONAL LOW FREQUENCY NOISE FILTERING.
THE SIGNAL DETECT OUTPUT ON THE HFBR-5911LZ CONTAINS AN INTERNAL 1.8 kW W PULL UP RESISTOR. THE OUTPUT STAGE ON THE HFBR5911L IS A PUSH PULL
CONFIGURATION AND THEREFORE DOES NOT REQUIRE AN EXTERNAL PULL UP RESISTOR.
