EBUS/LVDS transmit signals
EBUS/LVDS receive signals
BIAS resistor for EBUS-TX current adjustment
NOTE: An external LVDS termination with an impedance of 100 Ω between EBUS-RX+ and EBUS-RX- is
necessary for EBUS ports. EBUS-RX+ incorporates a pull-down resistor and EBUS-RX- incorporated a pull-up
resistor.
