HMC743ALP6CETR

HMC743ALP6CE v00.1212 Typical Applications Features The HMC743ALP6CE is ideal for: -45 to +18 dB Gain Control in 0.5 dB Steps • Cellular/3G Infrastructure Power-up State Selection • WiBro, WiMAX & LTE/4G High Output IP3: +33 dBm • Microwave Radio & VSAT TTL/CMOS Compatible Serial Control • Test Equipment and Sensors ±0.25 dB Typical Gain Step Error Single +5V Supply TE • IF & RF Applications 40 Lead 6x6 mm SMT Package: 36 mm2 Functional Diagram General Description B SO LE The HMC743ALP6CE is a digitally controlled variable gain amplifier which operates from DC to 4 GHz, can be programmed to provide 63 dB of gain control in 0.5 dB steps and delivers output IP3 of up to +33 dBm. The gain control interface accepts a three wire serial input word and allows independent or simultaneous control of two 6-bit digital attenuators. The HMC743ALP6CE also features a user selectable power up state and a serial output for cascading other serially controlled Hittite products. The HMC743ALP6CE is housed in an RoHS compliant 6x6 mm QFN leadless package, and requires minimal external components.

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. LE TE The HMC743ALP6CE can be serially controlled in one of two user-selectable modes: most significant bit first (MSBfirst), 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 attenuator(s) according to the truth table. The input and output attenuators can be controlled independently by applying this procedure separately for each attenuator and using the correct latch enable(LEA or LEB) , or a single control word can set both attenuators by first clocking in the 8-bit serial data word, then applying latch enable pulses to LEA and LEB, either one by one or simultaneously to change the content of the registers. O B SO MSB-First timing diagram ( BO = HIGH ) Information furnished by Analog Devices is believed to be accurate and reliable.
