SerD es chip used,see application note ofSerD es supplier.
Place R7/8/10/11 close to Infineon Transceiver
Figure 5
Values of R1/2/3/4 may vary as long as proper 50 W termination to V_EE or 100 W
differential is provided. The power supply filtering is required for good EMI performance.
Use short tracks from the inductor L1/L2 to the module V_CCRx/V_CCTx. We recommend a
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. (V_CCTx switched below V_TH).
Application Board available on request.
The stud pins S1 and S2 are not connected.
