• Manufacturer Part Number: v23826-k305-c13
• Description: Multimode 1.0625 Gbit/s Fibre Channel Gigabit Ethernet Transceiver
• Manufacturer: Infineon Technologies Corporation

Multimode 850 nm Gigabit Ethernet/Fibre Channel 1x9 Transceiver,
AC/AC TTL and AC/AC PECL Versions
Figure 7
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.

Place R1/2/3/4/7/8 close to SerDes chip.
Place R5/6 close to Infineon transceiver.
1) Design criterion of the capacitor used is the
resonant frequency and its value must be
in the order of the nominal data rate.
Short trace lengths are mandatory.
