4 GHz Serial Control Interface The HMC743ALP6CE contains a 3-wire SPI compatible digital interface (SERIN, CLK, LEA or LEB and BO) to control 8-bit word serial data. The input (IN) and output (OUT) attenuators can be individually controlled via the latch enable pins. The LEA pin latches the serial 8-bit word to the output attenuator. The LEB pin latches the serial 8-bit word to the input attenuator. The HMC743ALP6CE can be serially controlled in one of two user-selectable modes: most significant bit first (MSB- first), or least significant bit first (LSB-first). The serial data order is selected by control input BO (bit order select). BO = HIGH sets the MSB-first mode and the BO = LOW sets the LSB-first mode. After the 8-bit serial data is clocked in, the latch enable (LEA,LEB) is pulsed to set the state of........
