The ADAR4002 is a very low power broadband bi-directional single channel true time delay unit (TDU) and a digital step attenuator (DSA). The IC has 18.5 GHz of bandwidth over a frequency range of 0.5 GHz to 19 GHz with 50 ? input impedance at both RF ports. The TDU has two programmable maximum time delays, each with 7-bit control: Range 0 has a maximum delay of 508ps with a resolution of 4ps. This range is used at lower frequencies and where the ADAR4002 has less loss. Range 1 has a maximum delay of 254ps and a resolution of 2ps. This range has less loss compared to Range 0 and is useful at higher frequencies. The DSA has 6-bit resolution with an attenuation range of 0 dB to 31.5 dB and a step size of 0.5 dB. The ADAR4002 is designed to provide flexible digital control through either a SPI interface or a shift register to allow daisy chaining multiple chips together. The ADAR4002 contains register memory for 32 TDU+DSA states. The memory combined with on-chip sequencers, allows a fast memory advance via the UPDATE pin.The ADAR4002 is available in a 2 mm ? 3 mm 14-lead LFCSP package and is specified from -40?C to 85?C.APPLICATIONSElectronic steerable antenna arraysMulti-Function ArraysSATCOMRADARData LinksTest Equipment

The AD8122 is a triple, high speed, differential receiver and equalizer that compensates for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Each channel features a high impedance differential input that is ideal for interfacing directly with the cable.The AD8122 has two control inputs for optimal cable compensation, one LPF control input, an input to select between UTP and coax cable, and an output offset adjust input. The cable compensation inputs are used to compensate for different cable lengths; the VPEAK input controls the amount of high frequency peaking and the VGAIN input adjusts the broadband flat gain, which compensates for the flat cable loss. The VFILTER input controls the cutoff frequency of output lowpass filters on each channel. Selection between UTP and coaxial cable compensation responses is determined by the binary COAX/UTP?input, which can be left floating in UTP applications. The VOFFSET pin allows the dc voltage at the output to be adjusted, which can be useful in dc-coupled systems.For added flexibility, the gains of each channel can be set to x1 or x2 using the associated GAIN control pins.The AD8122 is available in a 6 mm ? 6 mm, 40-lead LFCSP and is rated to operate over the extended temperature range of ?40?C to +85?C.APPLICATIONS Keyboard-video-mouse (KVM) Digital signage RGB video over UTP cables Professional video projection and distribution HD video Security video

Demonstration Circuit 2611A features the LTC6955, Ultralow Jitter 11 Output Fanout Buffers. By default, the DC2611A is powered from a single 3.3V supply. An option is provided to power to the DC2611A from dual supplies, allowing for the LTC6955’s output supply pins to connect to an LTC Silent Switcher® and the LTC6955 input supply pin to connect to a low noise LDO. The differential inputs and six of the differential outputs are populated with 0.5" spaced SMA connectors. These outputs are AC-coupled with 50Ω transmission lines making them suitable to drive 50Ω impedance instruments. All registered trademarks and trademarks are the property of their respective owners. The remaining four differential outputs are terminated with 100Ω. A calibration path is provided to aid in accurate LTC6955 propagation delay measurements. The calibration path can be also reconfigured as a DC path, which allows for a convenient method of locking the LTC6955 outputs to an external PLL/VCO.
