PRODUCTION DATA.
When LO interface operates as input port, the pull-up resistors or inductors must be removed. Device pins must be AC coupled with DC block. LO pins offer wideband differential 100 Ohm termination to enable port matching. The value of termination can be set to 100Ohm, 200Ohm or high impedance through register EXTLO_INT_MATCH_RES (R123<1:0>). It is recommended to keep the termination setting to 100 ohm during external LO injection and to high impedance mode while LO is brought out from the device.
