The receive path consists of two independent, wide bandwidth (BW), direct conversion receivers with state-of-the-art dynamic range. The complete receive 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. RF front-end control and several auxiliary functions such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and general-purpose input/outputs (GPIOs) for the power amplifier (PA) are also integrated.In addition to automatic gain control (AGC), the ADRV9008-1 also features flexible external gain control modes, allowing significant flexibility in setting system level gain dynamically.The received signals are digitized with a set of four high dynamic range, continuous time, sigma-delta (?-?) ADCs that provide inherent antialiasing. The combination of the direct conversion architecture, which does not suffer from out of band image mixing, and the lack of aliasing relaxes the requirements of the RF filters compared to traditional intermediate frequency (IF) receivers.The fully integrated phase-locked loop (PLL) provides high per-formance, low power, fractional-N, RF synthesis for the receiver signal paths. An additional synthesizer generates the clocks needed for the converters, digital circuits, and the serial interface. A multi-chip synchronization mechanism synchronizes the phase of the RF local oscillator (LO) and baseband clocks between multiple ADRV9008-1 chips. Precautions are taken to provide the isolation required in high performance base station applications. All voltage controlled oscillators (VCOs) and loop filter components are integrated.The high speed JESD204B interface supports up to 12.288 Gbps lane rates, resulting in two lanes per transmitter and a single lane per receiver in the widest bandwidth mode. The interface also supports interleaved mode for lower bandwidths, reducing the total number of high speed data interface lanes to one. Both fixed and floating point data formats are supported. The floating point format allows internal AGC to be invisible to the demodulator device.The core of the ADRV9008-1 can be powered directly from 1.3 V and 1.8 V regulators and is controlled via a standard 4-wire serial port. Comprehensive power-down modes are included to mini-mize power consumption during normal use.

The wide differential input and common-mode ranges allow inputs to use the full (?VREF range without saturating, simplifying signal conditioning requirements and system calibration. The improved settling of the Easy Drive analog inputs broadens the selection of analog front-end components compatible with the AD4630-16. Both single-ended and differential signals are supported.The versatile Flexi-SPI serial peripheral interface (SPI) eases host processor and ADC integration. A wide data clocking window, multiple serial data output (SDO) lanes, and optional dual data rate (DDR) data clocking can reduce the serial clock to 10 MHz while operating at a sample rate of 2 MSPS. Echo clock mode can relax the timing requirements and simplify the use of digital isolators.The ball grid array (BGA) package of the AD4630-16 integrates all critical power supply and reference bypass capacitors, reducing the footprint and system component count, and lessening sensitivity to board layout.APPLICATIONS Automatic test equipment Digital control loops Medical instrumentation Seismology Semiconductor manufacturing Scientific instrumentation

DC1054A/B: Demo Board for the LTC4242 Dual Slot Hot Swap Controller for PCI Express.

The AD5172 / AD5173?are dual-channel, 256-position, one-time programmable (OTP) digital potentiometers that employ fuse link technology to achieve memory retention of resistance settings. The digital potentiometer, VR, and RDAC terms are used interchangeably. OTP is a cost-effective alternative to EEMEM for users who do not need to program the digital potentiometer setting in memory more than once. These devices perform the same electronic adjustment function as mechanical potentiometers or variable resistors but with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance.TheAD5172 / AD5173 are programmed using a 2-wire, I2C-compatible digital interface. Unlimited adjustments are allowed before permanently setting the resistance value. During OTP activation, a permanent blow fuse command freezes the wiper position (analogous to placing epoxy on a mechanical trimmer).Unlike traditional OTP digital potentiometers, the AD5172 / AD5173 have a unique temporary OTP overwrite feature that allows for new adjustments even after a fuse is blown. However, the OTP setting is restored during subsequent power-up conditions. This allows users to treat these digital potentiometers as volatile potentiometers with a programmable preset.APPLICATIONS Systems calibration Electronics level setting Mechanical trimmers replacement in new designs Permanent factory PCB setting Transducer adjustment of pressure, temperature, position, chemical, and optical sensors RF amplifier biasing Gain control and offset adjustment
