The AD8108/AD8109are high speed 8 × 8 video crosspoint switch matrices. They offer a −3 dB signal bandwidth greater than 250 MHz and channel switch times of less than 25 ns with 1% settling. With −83 dB of crosstalk and −98 dB isolation (at 5 MHz), the AD8108/AD8109 are useful in many high speed applications. The differential gain and differential phase of better than 0.02% and 0.02°, respectively, along with 0.1 dB flatness out to 60 MHz, make the AD8108/AD8109 ideal for video signal switching.The AD8108 and AD8109 include eight independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs so that off channels do not load the output bus. The AD8108 has a gain of 1, while the AD8109 offers a gain of 2. They operate on voltage supplies of ±5 V while consuming only 45 mA of idle current. The channel switching is performed via a serial digital control (which can accommodate daisy-chaining of several devices) or via a parallel control allowing updating of an individual output without reprogramming the entire array.The AD8108/AD8109 is packaged in an 80-lead LQFP and is available over the extended industrial temperature range of −40°C to +85°C.ApplicationsRouting of high speed signals includingComposite video (NTSC, PAL, S, SECAM)Component video (YUV, RGB)Compressed video (MPEG, Wavelet)3-level digital video (HDB3)

The AD812 is a low power, single supply, dual video amplifier. Each of the amplifiers have 50 mA of output current and are optimized for driving one back terminated video load (150 Ω) each. Each amplifier is a current feedback amplifier and features gain flatness of 0.1 dB to 40 MHz while offering differential gain and phase error of 0.02% and 0.02°. This makes the AD812 ideal for professional video electronics such as cameras and video switchers.The AD812 offers low power of 4.0 mA per amplifier max (VS= +5 V) and can run on a single +3 V power supply. The outputs of each amplifier swing to within one volt of either supply rail to easily accommodate video signals of 1 Vp-p. Also, at gains of +2 the AD812 can swing 3 V p-p on a single +5 V power supply. All this is offered in a small 8-pin plastic DIP or 8-pin SOIC package. These features make this dual amplifier ideal for portable and battery powered applications where size and power is critical.The outstanding bandwidth of 145 MHz along with 1600 V/µs of slew rate make the AD812 useful in many general purpose high speed applications where a single +5 V or dual power supplies up to ±15 V are available. The AD812 is available in the industrial temperature range of -40°C to +85°C.Lead free package option available (AD812ARZ, AD812ARZ-REEL, AD812ARZ-REEL7).

The AD8120 is a triple broadband skew delay compensation IC that corrects for time mismatch of video signals incurred by transmission in unshielded twisted pairs of Category-5 and Category-6 type cables. Skew between the individual pairs exists in most types of multi-pair UTP cables due to the different twist-rates used for each pair in order to minimize crosstalk among the pairs. Some pairs are therefore longer than others, and in long cables, the difference in propagation time between two pairs can be well into the tens of nanoseconds.The AD8120 contains three delay paths which provide broadband delays up to 50 nanoseconds, in 0.8 ns increments, using 64 digital control steps or analog control adjustment. The delay technique used in the AD8120 minimizes noise and offset at the outputs. It has a broad bandwidth that ranges between 106 MHz and 152 MHz, depending upon the delay setting. This high output bandwidth capability makes AD8120 ideal in applications that receive high-resolution video over UTP cables.The logic circuitry inside the AD8120 provides for individual delay control of each path. The three delay times can be independently set using a standard four-wire SPI bus, standard I2C bus or by applying three analog control voltages to the VCR, VCG, and VCBpins. Analog control offers a simple solution for systems that do not have digital control available, the simplest being potentiometer control.The AD8120 is designed to be used with the AD8123 triple UTP equalizer in video-over-UTP applications, but can be used in other applications where similar controllable broadband delays are required.The AD8120 is available in a 5 mm × 5 mm 32-lead LFCSP package and is rated to operate over the industrial temperature range of -40°C to +85°C.ApplicationsKeyboard-video-mouse (KVM)Digital signageRGB video over UTP cableProfessional video projection and distributionHD videoSecurity videoGeneral broadband delay linesData Sheet, Rev PrA, 10/2008
