SERDES Integrated Circuit Transceiver Interface and Power Supply Filter Circuits.
NOTES:
USE SURFACE-MOUNT COMPONENTS FOR OPTIMUM HIGH-FREQUENCY PERFORMANCE.
USE 50 MICROSTRIP OR STRIPLINE FOR SIGNAL PATHS.
LOCATE 50 TERMINATIONS AT THE INPUTS OF RECEIVING UNITS.
* IN ORDER TO ELIMINATE REQUIRED EXTERNAL PASSIVE COMPONENTS, AVAGO TECHNOLOGIES HAS INCLUDED THE EQUIVALENT OF RESISTORS R5 - R8 AND
CAPACITORS C5 AND C6 WITHIN THE MODULE. R5 - R8, C5 AND C6 ARE INCLUDED AS PART OF THE APPLICATION CIRCUIT TO ACCOMMODATE OTHER TRANSCEIVER
VENDORS' MODULES. THE HFBR-5912EZ WILL OPERATE IN BOTH CONFIGURATIONS.
**C8 IS A RECOMMENDED BYPASS CAPACITOR FOR ADDITIONAL LOW FREQUENCY NOISE FILTERING.
THE SIGNAL DETECT OUTPUT ON THE HFBR-5912EZ CONTAINS AN INTERNAL 1.8 k PULL UP RESISTOR.
