The AD8372 is a dual, digitally controlled, variable gainamplifier (VGA) that provides precise gain control, high IP3,and low noise figure. The excellent distortion performance andmoderate signal bandwidth make the AD8372 a suitable gain control device for a variety of multichannel receiverapplications.For wide input dynamic range applications, the AD8372provides a broad 41 dB gain range. The gain is programmedthrough a bidirectional 4-pin serial interface. The serial interface consists of a clock, latch, data input, and data output linesfor each channel. The AD8372 provides the ability to set the transconductance of the output stage using a single external resistor. The RXT1 and RXT2 pins provide a band gap derived stable reference voltage of 1.56 V. Typically 2.0 k? shunt resistors to ground are used toset the maximum gain to a nominal value of 31 dB. The currentsetting resistors can be adjusted to manipulate the gain anddistortion performance of each channel. This is a flexible feature in applications where it is desirable to trade off distortion performance for lower power consumption.The AD8372 is powered on by applying the appropriate logiclevel to the ENB1, ENB2 pins. When powered down, the AD8372consumes less than 2.6 mA and offers excellent input-to-outputisolation. The gain setting is preserved when powered down.Fabricated on an Analog Devices, Inc., high frequency BiCMOS process, the AD8372 provides precise gain adjustment capabilities with good distortion performance. The quiescent current of theAD8372 is typically 106 mA per channel. The AD8372 amplifier comes in a compact, thermally enhanced 5 mm ? 5 mm 32-leadLFCSP package and operates over the temperature range of ?40?C to +85?C.Applications Differential ADC drivers CMTS upstream direct sampling receivers CATV modem signal scaling Generic RF/IF gain stages Single-ended-to-differential conversion

The ADV7619 is a high quality, two input, one output (2:1) multiplexed High-Definition Multimedia Interface (HDMI?) receiver. The ADV7619 is offered in professional (no HDCP keys) and commercial versions. The operating temperature range is 0?C to 70?C.The ADV7619 incorporates a dual input HDMI-capable receiver that supports all mandatory 3D TV formats defined in the HDMI 1.4a specification, HDTV formats up to 1080p 36-bit Deep Color/2160p 8-bit, and display resolutions up to 4k ? 2k (3840 ? 2160 at 30 Hz). It integrates an HDMI CEC controller that supports the capability discovery and control (CDC) feature.The ADV7619 incorporates Xpressview? fast switching on both input HDMI ports. Using the Analog Devices, Inc., hardware-based HDCP engine to minimize software overhead, Xpressview technology allows fast switching between both HDMI input ports in less than 1 sec.Each HDMI port has dedicated 5 V detect and Hot Plug? assert pins. The HDMI receiver also includes an integrated programmable equalizer that ensures robust operation of the interface with long cables.The ADV7619 offers a flexible audio output port for audio data extraction from the HDMI stream. HDMI audio formats, including SACD via DSD and HBR, are supported by the ADV7619.The HDMI receiver has advanced audio functionality, such as a mute controller, that prevents audible extraneous noise in the audio output.The ADV7619 contains one main component processor (CP), which processes video signals from the HDMI receiver up to 1080p 36-bit Deep Color. It provides features such as contrast, brightness and saturation adjustments, STDI detection block, free-run, and synchronization alignment controls.For video formats with pixel clocks higher than 170 MHz, the video signals received on the HDMI receiver are output directly to the pixel port output.
