The ADRV9029 is a highly integrated, radio frequency (RF) agile transceiver offering four independently controlled transmitters, dedicated observation receiver inputs for monitoring each transmitter channel, four independently controlled receivers, integrated synthesizers, and digital signal processing functions providing a complete transceiver solution. The device provides the performance demanded by cellular infrastructure applications, such as small cell base station radios, macro 3G/4G/5G systems, and massive multiple in/multiple out (MIMO) base stations.The receiver subsystem consists of four independent, wide bandwidth, direct conversion receivers with wide dynamic range. The four independent transmitters use a direct conversion modulator resulting in low noise operation with low power consumption. The device also includes two wide bandwidth, time shared, observation path receivers with two inputs each for monitoring transmitter outputs.The complete transceiver subsystem includes automatic and manual attenuation control, dc offset correction, quadrature error correction (QEC), and digital filtering, eliminating the need for these functions in the digital baseband. Other auxiliary functions such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and general-purpose input/ outputs (GPIOs) that provide an array of digital control options are also integrated.To achieve a high level of RF performance, the transceiver includes five fully integrated phase-locked loops (PLLs). Two PLLs provide low noise and low power fractional-N RF synthesis for the transmitter and receiver signal paths. A third fully integrated PLL supports an independent local oscillator (LO) mode for the observation receiver. The fourth PLL generates the clocks needed for the converters and digital circuits, and a fifth PLL provides the clock for the serial data interface.A multichip synchronization mechanism synchronizes the phase of all LOs and baseband clocks between multiple ADRV9029 chips. All voltage controlled oscillators (VCOs) and loop filter components are integrated and adjustable through the digital control interface.This device contains a fully integrated, low power digital predistortion (DPD) adaptation engine for use in power amplifier linearization. DPD enables use of high efficiency power amplifiers, reducing the power consumption of base station radios while also reducing the number of SERDES lanes necessary to interface with baseband processors.The low power crest factor reduction (CFR) engine of the ADRV9029 reduces the peak to average ratio (PAR) of the input signal, enabling higher efficiency transmit line ups while reducing the processing load on baseband processors.The serial data interface consists of four serializer lanes and four deserializer lanes. The interface supports both the JESD204B and JESD204C standards, operating at data rates up to 24.33 Gbps. The interface also supports interleaved mode for lower bandwidths, thus reducing the number of high speed data interface lanes to one. Both fixed and floating-point data formats are supported. The floating-point format allows internal automatic gain control (AGC) to be invisible to the demodulator device.The ADRV9029 is powered directly from 1.0 V, 1.3 V, and 1.8 V regulators and is controlled via a standard serial peripheral interface (SPI) serial port. Comprehensive power-down modes are included to minimize power consumption in normal use. The ADRV9029 is packaged in a 14 mm ? 14 mm, 289-ball chip scale ball grid array (CSP_BGA).APPLICATIONS3G/4G/5G TDD and FDD massive MIMO, macro and small cell base stations

The ADP170 /?ADP171?/?ADP172 are low voltage input, low quiescentcurrent, low-dropout (LDO) linear regulators that operate from1.6 V to 3.6 V and provide up to 300 mA of output current. Thelow 55 mV dropout voltage at 300 mA load improves efficiencyand allows operation over a wide input voltage range. The low23 ?A of quiescent current at no load makes theADP170 / ADP171 / ADP172 ideal for battery-operated portableequipment.The ADP170 is capable of 31 fixed-output voltage options, ranging from 0.8 V to 3.0 V. ADP171 is an adjustableversion, which allows output voltages that range from 0.8 V to3.0 V via an external divider. The ADP170 / ADP171 areoptimized for stable operation with small 1 ?F ceramic outputcapacitors. Ideal for powering digital processors, the ADP170 / ADP171 exhibit good transient performance andoccupy minimal board space. Compared with commodity typesof LDOs, the ADP170 / ADP171 provide 20 dB to 40 dB betterpower supply rejection ratio (PSRR) at 100 kHz, making theADP170 / ADP171 an ideal power source for analog-to-digitalconverter (ADC) mixed-signal processor systems and allowinguse of smaller size bypass capacitors. In addition, low outputnoise performance without the need for an additional bypasscapacitor further reduces printed circuit board (PCB)component count.Short-circuit protection and thermal overload protectioncircuits prevent damage in adverse conditions.
