4 GHz Serial Control Interface The HMC743LP6C(E) contains a 3-wire SPI compatible digital interface (SERIN, CLK, LEA (or LEB)) that is used to control the input and output gain control elements (digital attenuators). The input (IN) and output (OUT) attenuators can be individually controlled thru the latch enable pins. The LEA pin latches the serial 6-bit control word to the output attenuator. The LEB pin latches the serial 6-bit control word to the input attenuator. The 6-bit serial word can be loaded either MSB first or LSB first depending on the state of the BO (bit order) pin. Setting BO to high configures the serial controller to operate in LSB first mode. Setting BO to low configures the serial controller to operate in MSB first mode. Timing Diagram PUP Truth Table Timing diagram is used for either input or output digital gain control. Control word is shown with MSB first (BO = Low) configuration.
