Y-RH850-U2A-292PIN-PB-T1-V1
Connected to RX_DATA_N
Connected to RX_DATA_P
Connected to TX_DATA_N
Connected to TX_DATA_P
Placed between Ethernet
transceiver and bridges RB3/RB4
Value 100nF
Uses 100 Ohm resistor to connect
RX_DATA_N and RX_DATA_P
Both pins are directly connected
to AWOVCL on the board.
Connected directly to GETH0VCL
on the board.
RH850/U2A16
RH850/U2A8
Y-RH850-U2A-292PIN-PB-T1-V2
Connected to RX_DATA_P
Connected to RX_DATA_N
Connected to TX_DATA_P
Connected to TX_DATA_N
Placed between RH850/U2A and
bridges RB3/RB4
Value 4.7nF
The pcb provides soldering points
to add a resistor between
RX_DATA_N and RX_DATA_P,
but by default this resistor is not
fitted.
A18 is connected to AWOVCL via
100 Ohm resistor. A18 and P12 are
connected to VSS.
Connected to GETH0VCL via 100
Ohm resistor and has a 220nF
capacitor to VSS. Provides the
possibility to connect pin E17 to
VSS via solder bridge RB5.
