C1/2/3 = 4.7 µF
L1/2 = 1 µH
R9 = 510 Ω (5 V), no resistor for TTL version
= 270 Ω (3.3 V)
Place R1/2/3/4/7/8 close to SerDes chip,
depends on SerDes chip used,
see application note of SerDes supplier.
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.

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.
