The ADV⑦⑤②⓪ is an ⑧⓪ MHz, High Definition Multimedia Interface (HDMI) transmitter with consumer electronic control (CEC). It supports HDTV formats up to ⑦②⓪p and ①⓪⑧⓪i and computer graphic resolutions up to XGA (①⓪②④ ⑦⑥⑧ @ ⑦⑤ Hz). With the inclusion of embedded HDCP keys, the ADV⑦⑤②⓪ allows the secure transmission of protected content, as specified by the HDCP ①.③ protocol.

The AD⑨⑤①⑦-③* provides a multi-output clock distribution function with subpicosecond jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from ①.⑦⑤ GHz to ②.②⑤ GHz. Optionally, an external VCO/VCXO of up to ②.④ GHz may be used.

The AD⑨⑤①① provides a multi-output clock distribution function along with an on-chip PLL core. The design emphasizes low jitter and low phase noise in order to maximize data converter clocking performance. Three independent LVPECL and two LVDS clock outputs operate to 1.2 GHz and ⑧⓪⓪ MHz respectively. Optional CMOS clock outputs available to ②⑤⓪ MHz.

The AD⑨⑨⑧③A is a complete ⑧-bit, ①④⓪ MSPS, monolithic analog interface optimized for capturing YPbPr video and RGB graphics signals. Its ①④⓪ MSPS encode rate capability and full power analog bandwidth of ③⓪⓪ MHz support all HDTV video modes up to ①⓪⑧⓪i and ⑦②⓪p as well as graphics resolutions up to SXGA (①②⑧⓪ x ①⓪②④ at ⑦⑤ Hz).

The ADuC⑧③⑥ MicroConverter is a fully integrated ①⑥-bit data acquisition system-on-a-chip. Like all of ADI's MicroConverter products, it features precision A/D D/A conversion and a Flash microcontroller on a single chip.

The AD⑨⑤①⑦-⓪* provides a multi-output clock distribution function with subpicosecond jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from ②.⑤⑤ GHz to ②.⑨⑤ GHz. Optionally, an external VCO/VCXO of up to ②.④ GHz may be used.

The AD⑧⑤⑥① is a single ⑦ ns comparator with separate input and output sections. Separate supplies enable the input stage to be operated from ⑤ V dual supplies and +⑤ V single supplies.

The AD⑦③⓪④/AD⑦③⓪⑤ are quad, ⑧-bit DACs that operate from a single +③ V to +⑤ V supply or ⑤ V supplies. The AD⑦③⓪④ has a serial interface, while the AD⑦③⓪⑤ has a parallel interface. Internal precision buffers swing rail-to-rail. The reference input range includes both supply rails allowing for positive or negative full-scale output voltages. Operation is guaranteed over the supply voltage range of +②.⑦ V, +⑤.⑤ V to ⑤ V consuming less than ⑨ mW from a +③ V supply. The full-scale voltage output is determined by the external reference input voltage applied. The rail-to-rail VREF input to DAC VOUT allows for a full-scale voltage set equal the positive supply VDD, the negative supply VSS or any value in between.

The AD⑧③②③ is a low cost digitally controlled variable gain amplifier optimized for coaxial line driving applications such as cable modems that are designed to the MCNS-DOCSIS upstream standard. A ⑧-bit serial word determines the desired output gain over a 5④ dB range resulting in gain changes of .⑦5 dB/LSB.

The ADCMP⑤⑤①/ADCMP⑤⑤②/ADCMP⑤⑤③ are single supply, high speed comparators fabricated on Analog Devices proprietary XFCB process. The devices feature a ⑦⑤⓪ ps propagation delay with less than ①⑤⓪ ps overdrive dispersion. Dispersion, a measure of the difference in propagation delay under differing overdrive conditions, is a particularly important characteristic of high speed comparators. A separate programmable hysteresis pin is available on the ADCMP⑤⑤②.

The AD⑧1⑨⑤ is an HDMI/DVI buffer featuring equalized TMDS inputs and preemphasized TMDS outputs, ideal for systems with long cable runs. The AD⑧1⑨⑤ includes bidirectional buffering for the DDC bus and bidirectional buffering with integrated pull-up resistors for the CEC bus. The DDC and CEC buffers are powered independently of the TMDS buffers so that DDC/CEC functionality can be maintained when the system is powered off.

The AD⑨⑧⑥⓪/AD⑨⑧⑥② are versatile integrated mixed signal front ends that are optimized for broadband wireless applications. The AD⑨⑧⑥⓪/AD⑨⑧⑥② are cost effective high performance mixed signal solutions for standards based or proprietary fixed access, modem, or wireless networking applications where dynamic performance, power dissipation, cost, and size are critical attributes.

The ADCMP⑤⑧⓪/ADCMP⑤⑧①/ADCMP⑤⑧② are ultrafast voltage comparators fabricated on the Analog Devices, Inc. proprietary XFCB③ Silicon Germanium (SiGe) bipolar process. The ADCMP⑤⑧⓪ features CML output drivers, the ADCMP⑤⑧① features reduced swing ECL (negative ECL) output drivers, and the ADCMP⑤⑧② features reduced swing PECL (positive ECL) output drivers.

The AD⑨⑤④⑨ provides synchronization for many systems, including synchronous optical networks (SONET/SDH). The AD⑨⑤④⑨ generates an output clock, synchronized to one of two external input references. The external references may contain significant time jitter, also specified as phase noise. Using a digitally controlled loop and holdover circuitry, the AD⑨⑤④⑨ continues to generate a clean (low jitter), valid output clock during a loss of reference condition, even when both references have failed.

The AD⑤⑤⑦ DACPORT is a complete voltage-output ⑧-bit digital-to-analog converter, including output amplifier, full microprocessor interface and precision voltage reference on a single monolithic chip. No external components or trims are required to interface, with full accuracy, an ⑧-bit data bus to an analog system.

The AD⑦⑧①① and AD⑦⑧①② are high speed, low power, ①⓪-bit A/D converters that operate from a single ②.⑦ V to ⑤.⑤ V supply. The devices contain a ②.③ s successive approximation A/D converter, an on-chip track/hold amplifier, a ②.⑤ V on-chip reference and a high speed serial interface that is compatible with the serial interfaces of most DSPs (Digital Signal Processors) and microcontrollers. The user also has the option of using an external reference by connecting it to the VREF pin and setting the EXTREF bit in the control register. The VREF pin may be tied to VDD. At slower throughput rates the power-down mode may be used to automatically power down between conversions.

The AD⑦③③⑨ is a composite IC that contains both DAC and ADC functions. The device includes an ⑧-bit parallel A-to-D converter. Two ⑧-bit parallel DACs are also included as are two serial control DACs. These serial DACs are ⑧-bit DACs.

The AD⑦⑨⓪ is a fast (④⑤ ns), precise voltage comparator, with a number of features that make it exceptionally versatile and easy to use. The AD⑦⑨⓪ may operate from either a single +⑤ V supply or a dual ①⑤ V supply. In the single-supply mode, the AD⑦⑨⓪'s inputs maybe referred to ground, a feature not found in other comparators. In the dual-supply mode it has the unique ability of handling a maximum differential voltage of ①⑤ V across its input terminals, easing their interfacing to large amplitude and dynamic signals.

The AD⑧①④⑤ is a triple, low cost, differential-to-single-ended receiver specifically designed for receiving red-green-blue (RGB) video signals over twisted pair cable or differential printed circuit board traces. It can also be used to receive any type of analog signal or high speed data transmission. Two auxiliary comparators with hysteresis are provided that can be used to decode video sync signals that are encoded on the received common-mode voltages, to receive digital signals, or as general-purpose comparators. The AD⑧①④⑤ can be used in conjunction with the AD⑧①③③ or AD⑧①③④ triple differential drivers to provide a complete low cost solution for RGB over Category ⑤ UTP cable applications, including KVM.
