The ADuM130x are triple-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocouplers.By avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple iCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler devices consume one-tenth to one-sixth of the power of optocouplers at comparable signal data rates.The ADuM130x isolators provide three independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide in the data sheet). Both models operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. In addition, the ADuM130x provide low pulse width distortion (<2 ns for CRW grade) and tight channel-to-channel matching (<2 ns for CRW grade). Unlike other optocoupler alternatives, the ADuM130x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and when power is not applied to one of the supplies.APPLICATIONS General-purpose multichannel isolation SPI interface/data converter isolation RS-232/RS-422/RS-485 transceivers Industrial field bus isolation Automotive systems

The AD6623 is a four channel Transmit Signal Processor (TSP) that creates high bandwidth data for Transmit Digital-to-Analog Converters (TxDAC®s) from baseband data provided by a Digital Signal Processor (DSP). Modern TxDACs have achieved sufficiently high sampling rates, analog bandwidth, and dynamic range to create the first Intermediate Frequency (IF) directly. The AD6623 synthesizes multi-carrier and multi-standard digital signals to drive these TxDACs. The RAM-based architecture allows easy reconfiguration for multi-mode applications. Modulation, pulse-shaping and anti-imaging filters, static equalization, and tuning functions are combined in a single, cost-effective device. Digital IF signal processing provides repeatable manufacturing, higher accuracy, and more flexibility than comparable high dynamic range analog designs.The AD6623 is pin compatible to the AD6622 and can operate in AD6622 compatible control register mode. Each TSP has five cascaded signal processing elements: a programmable interpolating RAM Coefficient Filter (RCF), a programmable Scale and Power Ramp, a programmable 5th order Cascaded Integrator Comb (CIC5) interpolating filter, a flexible 2nd order Re-Sampling Cascaded Integrator Comb filter (rCIC2), and a Numerically Controlled Oscillator/tuner (NCO). The AD6623 has four identical digital TSPs complete with synchronization circuitry and cascadable wideband channel summation. The outputs of the four TSPs are summed and scaled on-chip. In multi-carrier channel wideband transmitters, a bi-directional bus allows the Parallel (wideband) IF Input/Output to drive a second DAC. In this operational mode two AD6623 channels drive one DAC and the other two AD6623 channels drive a second DAC. Multiple AD6623s may be combined by driving the INOUT[17:0] of the succeeding with the OUT[17:0] of the preceding chip. The INOUT[17:0] can alternatively be masked off by software to allow preceding AD6623s outputs to be ignored.Each channel accepts input data from independent serial ports that may be connected directly to the serial port of Digital Signal Processor (DSP) chips. The AD6623 utilizes a 3.3V I/O power supply and a 2.5V core power supply. All I/O pins are 5V tolerant. All control registers and coefficient values are programmed through a generic microprocessor interface. Intel and Motorola microprocessor bus modes are supported. All inputs and outputs are LVCMOS compatible.Applications Cellular/PCS Base Stations Micro/Pico Cell Base Stations Wireless Local Loop Base Stations Multicarrier, Multimode Digital Transmit GSM, EDGE, IS136, PHS, IS95, TDS CDMA, UMTS, CDMA2000 Phased Array Beam Forming Antennas Software Defined Radio Tuning Resolution Better than 0.025 Hz Real or Complex Outputs
