• Manufacturer Part Number: V23826-K305-C353
• Description: Multimode 850 nm 1.0625 Gbit/s Fibre Channel 1.3 Gigabit Ethernet 1x9 Transceiver
• Manufacturer: INFINEON [Infineon Technologies AG]

Multimode 850 nm Gigabit Ethernet/Fibre Channel 1x9 Transceiver,
AC/DC Version
Figure 6
Values of R1/2/3/4 may vary as long as proper 50
differential is provided. The power supply filtering is required for good EMI performance.
Use short tracks from the inductor L1/L2 to the module
The transceiver contains an automatic shutdown circuit. Reset is only possible if the
power is turned off, and then on again. (
Application Board available on request.
