Abstract
A method and an apparatus for supplying power to a 300 PIN MSA 40 Gb TRANSPONDER (22), wherein the apparatus comprises a power supply control module (21), a first resistor (R2), a second resistor (R3) and a third resistor (R4). The power supply control module (21) supplies power to the TRANSPONDER (22) through the APS Digital pin (APS Digital) of the TRANSPONDER (22). A reference voltage terminal (Vfeedback) of the power supply control module (21) is connected to the APS Sense pin (APS Sense) of the TRANSPONDER (22) by the second resistor (R3), connected to the APS Set pin (APS Set) of the TRANSPONDER (22) by the first resistor (R2) and connected to the bias voltage terminal (Vbias) of the power supply control module (21) by the third resistor (R4). The method and the apparatus can increase selection of the power supply control module (21) without occupying excessive space of circuit board, while ensuring precision of supply voltage.
