V23826-K15-Cxx, V23826-K15-Cxxx Product Specification – August 2004
Single Mode 1300 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
GND plane under the module for getting good EMI performance.
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.
The stud pins S1 and S2 are not connected.
