The ADATE209 dual 3-level Pin Driver is designed for testing DDR2/DDR3 memory, PCI Express 1.0, HDMI, and other high-speed devices. Able to deliver high-fidelity output swings of 200 mV to 4 V over a –1-V to +3.5-V range, it specifies: 120-ps max rise/fall times and 4.4-Gbps data rate with a 2-V swing; 150-ps max rise/fall times and 3.2-Gbps data rate with a 3-V swing; and high-speed transitions into/out of term mode. Peaking- and pre-emphasis circuitry compensates for cable losses.
The ADATE302/ADATE304/ADATE305 Pin-Electronics SoCs perform the automatic-test-equipment (ATE) functions of driver, comparator, and active load (DCL)—at speeds of up to 500/250/250 MHz. It also provides a per-pin parametric measurement unit (PMU) and dc level setting. The proprietary driver features three active-mode output levels—logic high, logic low, and term—and a high-impedance inhibit mode. Its –2-V to +6-V output range accommodates a wide variety of test devices. High-speed window- and differential comparators facilitate functional testing. The PMU can force or measure voltage or current—and measure voltage or current—on a per-pin basis. On-chip 14-bit DACs set the dc levels for the driver, comparator, and active load (DCL); a 16-bit DAC provides precision levels for the PMU. Each dual device can be used to support two single-ended drive/receive channels or a single differential channel.

The AD8192 buffered HDMI/DVI Switch selects one of two HDMI (high-definition-multimedia-interface) or DVI (digital-visual-interface) input links—each comprising four TMDS (transition-minimized-differential-signaling) channels—and routes it to a common output link. Input equalization and output pre-emphasis make possible the use of long (>20-m) cables. Supporting data rates up to 2.25 Gbps and pixel clocks up to 225 MHz, it enables DVI resolutions up to UXGA (1600 × 1200) and HDMI formats up to 1080p deep color. It also selects one of two bidirectional auxiliary links—for the DDC (display-data-channel) bus and CEC (consumer electronics control) line—thus implementing a complete HDMI 1.3-compliant interface on a single chip. The auxiliary buffers are powered independently of the TDMS link, maintaining DDC/CCE functionality when the TMDS link is powered off.

The
ADP2121 step-down DC-to-DC
Converter is available in 1.80-V, 1.82-V, 1.85-V, and 1.875-V fixed-output
versions. It uses 6-MHz pulse-width-modulation (PWM) to provide high stability
and fast transient response, switching to pulse-frequency modulation (PFM) to
improve efficiency under light-load conditions. Requiring only three passive
external components, it can provide 500-mA output current at 92% efficiency. Its
robust design features a fixed 300-µs soft-start time, short-circuit- and
thermal-overload protection, and under-voltage lockout. Low quiescent current
(38 µA with no load) and 0.28-μA shutdown current make it ideal for
battery-powered equipment.

The ADuM5000 isoPower™ isolated DC-to-DC-Converter uses patented iCoupler® technology, which combines high-speed CMOS with integrated micro-transformers to provide 500 mW of isolated, regulated power. The regulated outputs are 3.3 V or 5 V with a 5-V input supply, or 3.3 V with a 3.3-V input. The ADuM5000 can be combined with the ADuM520x and ADuM540x isolators to achieve higher output power.
The ADuM520x two-channel Digital Isolators integrate a 500-mW isoPower™ dc-to-dc converter, offering a complete isolation solution in a tiny package. Providing an isolated power supply and superior performance to optocouplers, they use patented iCoupler® technology, which combines high-speed CMOS with integrated micro-transformers. This technology eliminates the uncertain current-transfer ratios, nonlinear transfer functions, and drift (with time and temperature) associated with optocouplers. Power consumption is up to 90% lower, and no external drivers or discrete devices are required. The 2500 Vrms isolation channel meets safety- and regulatory requirements of UL, CSA, and VDE. Featuring 40-ns pulse-width distortion and 25-kV/μs common-mode transient immunity, they can handle data rates from dc to 25 Mbps (C-grade only). A variety of channel configurations and data rates are available.

The ADM2482E/ADM2487E Isolated RS-485 Transceivers employ iCoupler® technology to integrate a 3-channel isolator with a 3-state differential line driver and a differential-input line receiver. An on-chip oscillator provides two square-wave outputs that drive an external transformer to provide isolated power. Operating at data rates up to 500 kbps/16 Mbps, the transceivers enable full- or half-duplex data communication over multipoint-bus transmission lines. Designed for balanced transmission, they comply with ANSI/TIA/EIA RS-485 and ISO 8482 standards. The line inputs and outputs provide ±15-kV ESD protection, 2.5-kV isolation, and 25-kV/μs transient immunity, making the device suitable for operation in electrically harsh environments.
The ADM3251E high-speed, single-channel, Isolated RS-232 Line Driver/Receiver is ideally suited to operate in electrically harsh environments—or where RS-232 cables are frequently plugged in or unplugged. Integrating a 2-channel iCoupler digital isolator and an isoPower chip-scale dc-to-dc converter, it eliminates the need for an external dc-to-dc converter. Communicating at data rates up to 460 kbps, it conforms to EIA-232E specifications. The transmit and receive pins are protected against ESD events up to ±15 kV. Operating on a single power supply, it provides signal- and power isolation in a small form factor.
The ADuM5230 Isolated Half-Bridge Driver uses iCoupler® technology to provide independent, isolated outputs for driving the gates of the high-side and low-side IGBT and MOSFET devices used in plasma displays, switching power supplies, and solar-panel inverters. The integrated dc-to-dc converter provides an isolated high-side power supply that can power both the ADuM5230 and external buffer circuitry. Combining high-speed CMOS with monolithic micro-transformers, iCoupler technology provides precise timing, high reliability, and better overall performance than optocoupler-based systems. Each output can be operated up to ±700 VP with respect to its input, with a differential of up to 700 VP between the high side and the low side. Switching at up to 1 MHz, the outputs can source 100 mA and sink 300 mA. The CMOS-compatible inputs provide 25-kV/µs common-mode transient immunity.
The ADuM6132 Isolated Half-Bridge Driver provides an isolated output for driving the high-side FET—and a non-isolated output for driving the low-side FET—in motor drives, switching power supplies, and solar-panel inverters. The integrated dc-to-dc converter provides an isolated high-side power supply that can power both the ADuM6132 and external buffer circuitry. The differential voltage between high- and low sides can be as high as ±1,131 VP. Switching at up to 1 MHz, the outputs can source and sink 200 mA. The CMOS-compatible inputs provide 25-kV/µs common-mode transient immunity. The isolation uses iCoupler® technology to provide precise timing, high reliability, and better overall performance than optocoupler-based systems.

The ADM1184 four-channel Voltage Monitor uses precision comparators to monitor four supply voltages with 0.8% accuracy. Three open-drain outputs, which can be used to enable power supplies, are asserted when their associated inputs rise above the thresholds set by external resistors. An open-drain power-good output is asserted when all four monitored voltages remain above their programmed thresholds for 190 ms; it is de-asserted immediately if any input drops below its threshold.

For reliable operation, the controller provides protection against excessive current, over-voltage, and under-voltage, and includes built-in checksum and critical-circuit redundancy. The digital loop filter, PWM signal timing, inrush current, soft start timing, and sequencing can all be programmed using on-chip memory.

The ADL5360 dual Balanced Mixer accepts RF main- and diversity inputs in the 700-MHz to 1000-MHz range and mixes them with a local oscillator (LO) in the 250-MHz to 960-MHz range to produce IF main- and diversity outputs in the 40-MHz to 450-MHz range. The balanced design reduces typical LO to RF leakage to –25 dBm. High-linearity IF buffer amps follow the passive mixer cores, yielding 9.5-dB typical power conversion gain. On-chip RF baluns enable single-ended operation. Two switched LO paths facilitate time time-domain duplexing (TDD) applications.
