The ADV3202/ADV3203 are 32 ? 16 analog crosspoint switch matrices. They feature a selectable sync-tip clamp input forac-coupled applications and a 2:1 on-screen display (OSD) insertion mux. With ?48 dB of crosstalk and ?80 dB isolationat 5 MHz, the ADV3202/ADV3203 are useful in many high density routing applications.

The ADV3202 has a gain of +1 while the ADV3203 has a gain of +2 for ease of use in back-terminated load applications. A single +5 V supply, dual ?2.5 V supplies, or dual ?3.3 V supplies can be used while consuming only 195 mA of idle current with all outputs enabled. The channel switching is performed via a double buffered, serial digital control, that can accommodate daisy chaining of several devices.The ADV3202/ADV3203 are packaged in a 176-lead exposed pad LQFP package (24 mm ? 24 mm) and are available over the extended industrial temperature range of ?40?C to +85?C.Applications CCTV surveillance Routing of high speed signals ?Composite video (NTSC, PAL, S, SECAM) ?RGB and component video routing ?Compressed video (MPEG, wavelet) Video conferencingData Sheet, Rev 0, 11/2008

ADZS-AD2428MINI is a low-cost, mini break-out board which can interface with EV-SOMCRR-EZKIT (via a 100-pin connector) or any custom board (via a 32 pin 0.1" header). It supports main and subordinate node capability as well as bus and local power configurations. An Automotive Audio Bus (A2B®) system consists of a single main node and at least one subordinate node, where the transceiver at the host controller is the main node. The main transceiver generates clock, synchronization, and framing for all subordinate nodes and is programmable over a control bus (I2C) for configuration and readback. An extension of this control bus is embedded in the A2B data stream, which enables the host to directly access subordinate transceiver registers and any I2C-connected peripherals on subordinate nodes. Transceivers can connect directly to PDM microphones and to numerous peripherals via I2C and a multichannel I2S/TDM interface. Finally, the transceiver also supports an A2B bus powering feature, where the main node supplies voltage and current to the subordinate nodes over the same daisy-chained, twisted pair wire cable as used for the communication link, thus eliminating the need for a power supply on bus-powered subordinate nodes. Due to the numerous configurations that are possible for a given A2B system, there are several evaluation platforms that can be used in combination to verify system operation, as summarized in the table below.

The LTC1066-1 is an 8th order elliptic lowpass filter which simultaneously provides clock-tunability and DC accuracy. The unique and proprietary architecture of the filter allows 14 bits of DC gain linearity and a maximum of 1.5mV DC offset. An external RC is required for DC accurate operation. With ?7.5V supplies, a 20k resistor and a 1?F capacitor, the cutoff frequency can be tuned from 800Hz to 100kHz. A clock-tunable 10Hz to 100kHz operation can also be achieved (see Typical Application section).The filter does not require any external active components such as input/output buffers. The input/output impedance is 500M?/0.1? and the output of the filter can source or sink 40mA. When pin 8 is connected to V+ , the clock-to-cutoff frequency ratio is 50:1 and the input signal is sampled twice per clock cycle to lower the risk of aliasing. For frequencies up to 0.75fCUTOFF , the passband ripple is ?0.15dB. The gain at fCUTOFF is -1dB and the filter?s stopband attenuation is 80dB at 2.3fCUTOFF . Linear phase operation is also available with a clock-to-cutoff frequency ratio of 100:1 when pin 8 is connected to ground.The LTC1066-1 is available in an 18-pin SO Wide package..Applications Instrumentation Data Acquisition Systems Anti-Aliasing Filters Smoothing Filters Audio Signal Processing

High frequency switching allows for very small inductors to be used. All surface mount components consume less than 0.5 square inch of board space.New design techniques increase flexibility and maintain ease of use. Switching is easily synchronized to an external logic level source. A logic low on the shutdown pin reduces supply current to 12?A. Unique error amplifier circuitry can regulate positive or negative output voltage while maintaining simple frequency compensation techniques. Nonlinear error amplifier transconductance reduces output overshoot on start-up or overload recovery. Oscillator frequency shifting protects external components during overload conditions.Applications Boost Regulators CCFL Backlight Driver Laptop Computer Supplies Multiple Output Flyback Supplies Inverting Supplies

The LTC1174 is a simple current mode DC/DC converter ideally suited for 9V to 5V, 5V to 3.3V or 5V to ?5V operation. With an internal 0.9? switch (at a supply voltage of 9V), the LTC1174 requires only four external components to construct a complete high efficiency DC/DC converter.Under a no load condition the LTC1174 draws only 130?A.

The LTC1435 is a synchronous step-down switching regulator controller that drives external N-channel power MOSFETs using a fixed frequency architecture. Burst Mode? operation provides high efficiency at low load currents. A maximum duty cycle limit of 99% provides low dropout operation which extends operating time in battery-operated systems.The operating frequency is set by an external capacitor allowing maximum flexibility in optimizing efficiency. A secondary winding feedback control pin, SFB, guarantees regulation regardless of load on the main output by forcing continuous operation. Burst Mode operation is inhibited when the SFB pin is pulled low which reduces noise and RF interference.Soft start is provided by an external capacitor which can be used to properly sequence supplies. The operating current level is user-programmable via an external current sense resistor. Wide input supply range allows operation from 3.5V to 30V (36V maximum).For a guaranteed and test minimum on-time refer to the LTC1435A, the 'A' version of the LTC1435. The minimum on-time of the LTC1435A is guaranteed to be ?300ns. The only difference between these two parts is this guaranteed minimum on-time.
