The LTC4063 is a standalone linear charger for single cell lithium-ion batteries with an adjustable low dropout linear regulator (LDO). The adjustable LDO regulates an output voltage between 1.2V to 4.2V at up to 100mA load current. When the input supply (wall adapter or USB supply) is removed, the LDO regulates the output voltage without interruption. The battery charger and LDO regulator can be enabled individually.No external sense resistor or external blocking diode is required for charging due to the internal MOSFET architecture. Internal thermal feedback regulates the charge current to maintain a constant die temperature during high power operation or high ambient temperature conditions. The float voltage is fixed at 4.2V and the charge current is programmed with an external resistor. Charge termination methods include minimum charge current or maximum time. With power applied, the LTC4063 can be put into shutdown mode to reduce the supply current to 35?A and the battery drain current to less than 2?A.Other features include smart recharge, undervoltage lockout, LDO current limiting and a charge status pin to indicate when the charge cycle has completed.Applications Handheld Computers Portable MP3 Players Digital Cameras

The AD8122 is a triple, high speed, differential receiver and equalizer that compensates for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Each channel features a high impedance differential input that is ideal for interfacing directly with the cable.The AD8122 has two control inputs for optimal cable compensation, one LPF control input, an input to select between UTP and coax cable, and an output offset adjust input. The cable compensation inputs are used to compensate for different cable lengths; the VPEAK input controls the amount of high frequency peaking and the VGAIN input adjusts the broadband flat gain, which compensates for the flat cable loss. The VFILTER input controls the cutoff frequency of output lowpass filters on each channel. Selection between UTP and coaxial cable compensation responses is determined by the binary COAX/UTP?input, which can be left floating in UTP applications. The VOFFSET pin allows the dc voltage at the output to be adjusted, which can be useful in dc-coupled systems.For added flexibility, the gains of each channel can be set to x1 or x2 using the associated GAIN control pins.The AD8122 is available in a 6 mm ? 6 mm, 40-lead LFCSP and is rated to operate over the extended temperature range of ?40?C to +85?C.APPLICATIONS Keyboard-video-mouse (KVM) Digital signage RGB video over UTP cables Professional video projection and distribution HD video Security video

The ADRV9009 is a highly integrated, radio frequency (RF), agile transceiver offering dual transmitters and receivers, integrated synthesizers, and digital signal processing functions. The IC delivers a versatile combination of high performance and low power consumption demanded by 3G, 4G, and 5G macro cell time division duplex (TDD) base station applications.The receive path consists of two independent, wide bandwidth, direct conversion receivers with state-of-the-art dynamic range. The device also supports a wide bandwidth, time shared observation path receiver (ORx) for use in TDD applications. The complete receive subsystem includes automatic and manual attenuation control, dc offset correction, quadrature error correction (QEC), and digital filtering, thus eliminating the need?for these functions in the digital baseband. Several auxiliary functions, such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and general-purpose inputs/outputs (GPIOs) for the power amplifier (PA), and RF front-end control are also integrated.In addition to automatic gain control (AGC), the ADRV9009 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 ?-? 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 when compared to traditional intermediate frequency (IF) receivers.The transmitters use an innovative direct conversion modulator that achieves high modulation accuracy with exceptionally low noise.The observation receiver path consists of a wide bandwidth, direct conversion receiver with state-of-the-art dynamic range.The fully integrated phase-locked loop (PLL) provides high performance, low power, fractional-N RF frequency synthesis for the transmitter (Tx) and receiver (Rx) signal paths. An additional synthesizer generates the clocks needed for the converters, digital circuits, and the serial interface. A multichip synchronization mechanism synchronizes the phase of the RF local oscillator (LO) and baseband clocks between multiple ADRV9009 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, thus 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 ADRV9009 can be powered directly from 1.3 V regulators and 1.8 V regulators, and is controlled via a standard 4-wire serial port. Comprehensive power-down modes are included to minimize power consumption in normal use.
