The HMC621LP4E is a highly integrated downconverter IC that operates from 0.9 to 1.6 GHz. The HMC621LP4E incorporates a high dynamic range, single-balanced mixer core with integrated RF, LO and IF amplifiers, making it ideal for compact transceiver applications in Cellular//3G & LTE/WiMAX/4G. This versatile converter RFIC operates with a low LO input power level of only 0 dBm, provides 30 dB conversion gain, and exhibits +33 dBm output IP3. The integrated RF amplifier provides for an overall noise figure of only 4.5 dB.Applications Cellular/3G and LTE/WiMAX/4G BTS & Infrastructure Repeaters and Femtocells Public Safety Radio Access Points 

The ADG2128 is an analog cross point switch with an array size of 8 × 12. The switch array is arranged so that there are eight columns by 12 rows, for a total of 96 switch channels. The array is bidirectional, and the rows and columns can be configured as either inputs or outputs. Each of the 96 switches can be addressed and configured through the I2C compatible interface. Standard, full speed, and high speed (3.4 MHz) I2C interfaces are supported. Any simultaneous switch combination is allowed. An additional feature of the ADG2128 is that switches can be updated simultaneously, using the LDSW command. In addition, a RESET option allows all of the switch channels to be reset/off. At power-on, all switches are in the off condition. The device is packaged in a 32-lead, 5 mm × 5 mm LFCSP_VQ.APPLICATIONS AV switching in TV Automotive infotainment AV receivers CCTV Ultrasound applications KVM switching Telecom applications Test equipment/instrumentation PBX systems

The ADT74701 controller is a multichannel temperature sensor and PWM fan controller and fan speed monitor for systems requiring active cooling. It is designed to interface directly to an I2C® bus. The ADT7470 can monitor up to 10 daisy-chained TMP05 temperature sensors. It can also monitor and control the speed of four fans, in automatic or in manual control loops.A FULL_SPEED input is provided to allow the fans to be blasted to maximum speed, via external hardware control, under extreme thermal conditions or on system startup. An SMBALERT interrupt communicates error conditions such as fan under speed and over temperature measurements to the system service processor. Individual error conditions can then be read from status registers over the I2C bus.APPLICATIONS Servers Networking and telecommunications equipment Desktops

The AD725 is a very low cost general purpose RGB to NTSC/PAL encoder that converts red, green and blue color componentsignals into their corresponding luminance (basebandamplitude) and chrominance (subcarrier amplitude and phase)signals in accordance with either NTSC or PAL standards.These two outputs are also combined on-chip to provide acomposite video output. All three outputs are available separatelyat voltages of twice the standard signal levels as requiredfor driving 75 Ω, reverse-terminated cables.An evaluation board is available for this product and may be ordered using the following product number: AD725-EB.

The AD8110 and AD8111 are high-speed 16 × 8 video crosspointswitch matrices. They offer a –3 dB signal bandwidthgreater than 260 MHz, and channel switch times of less than25 ns with 1% settling. With –78 dB of crosstalk and –97 dBisolation (@ 5 MHz), the AD8110/AD8111 are useful in manyhigh-speed applications. The differential gain and differentialphase of better than 0.02% and 0.02° respectively, along with0.1 dB flatness out to 60 MHz, make the AD8110/AD8111ideal for video signal switching.The AD8110 and AD8111 include eight independent outputbuffers that can be placed into a high impedance state for parallelingcrosspoint outputs so that off channels do not load theoutput bus. The AD8110 has a gain of +1, while the AD8111offers a gain of +2. They operate on voltage supplies of ±5 Vwhile consuming only 50 mA of idle current. The channelswitching is performed via a serial digital control (which canaccommodate “daisy chaining” of several devices) or via a parallelcontrol, allowing updating of an individual output without reprogrammingthe entire array.The AD8110/AD8111 is packaged in an 80-lead LQFP packageand is available over the extended industrial temperature rangeof –40°C to +85°C.Applications Routing of high-speed signals including: Composite video (NTSC, PAL, S, SECAM) Component video (YUV, RGB) Compressed video (MPEG, Wavelet) 3-level digital video (HDB3)
