065TSMC_CML_01 core logic interface includes complementary output signal pins (OUTp, OUTn) for data transmission and enable pin EN_RX. PAD_INP and PAD_INN are differential input pins that should be connected to bonding pads. Buffer includes two 50-Ohm on-chip termination resistors, connected to supply voltage node. So the interface supports both AC and DC-coupled connections. IREF_RX is a reference current input.
