The design advances of component pick-and-place automated equipment for board assembly increasingly are pushing the margins of the tape-and-reel packing configurations. The continuing drive for faster assembly reduces the index time and tends to amplify the forces acting on the tape-and-reel component-delivery system. The magnified forces when combined with a high carrier-tape width-to-component

Demonstration Circuit DC2100B-D is a stackable, bidirectional cell balancer slave board using the LTC6804-2 and the LTC3300-1 ICs to achieve active balancing of up to 12 Li-Ion cells. It requires the DC2100B-C for proper operation. The DC2100B-D uses a single LTC6804-2 Multi-Cell Addressable Battery Stack Monitor IC to measure cell voltages and two LTC3300-1 Synchronous Flyback ICs to provide active cell balancing. The DC2100B-C controller board contains a PIC18F47J53 microcontroller, the LTM2884 isolated USB transceiver, the LTC6804-2, two LTC3300-1 ICs, and the LTC6820 isoSPI Interface IC to facilitate isolated communication. Up to seven DC2100B-D boards can be connected to a DC2100B-C to build a stacked system of eight total boards.

Demonstration circuit 1340 is a triple output regulator consisting of three constant-frequency step-down converters integrated into LTC3569. DC1340 has an input voltage range of 2.5V to 5.5V, with regulators capable of delivering 1.2A or 600mA of load current on corresponding output. The three regulators operate independently with individual Enable pins and enter pulse skipping or burst mode at low loads for increasing efficiency. The DC1340 is a very efficient circuit with efficiency reading above 90%. High operating frequency of 2.25MHz allows exclusive use of the small size, low profile surface mount components. These features plus internal compensation circuits and extremely low quiescent current make the DC1340 demo board an ideal circuit for use in battery-powered, hand-held applications.

The ADAR1000 is a 4-channel, X and Ku frequency band, beamforming core chip for phased arrays. This device operates in half-duplex between receive and transmit modes. In receive mode, input signals pass through four receive channels and are combined and output at the common RF_IO pin. In transmit mode, the RF_IO input signal is split and passes through the four transmit channels. In both modes, the ADAR1000 provides a ?31 dB gain adjustment range and a full 360? phase adjustment range in each radio frequency (RF) channel, with 6-bit resolution (less than ?0.5 dB and 2.8?, respectively).A simple 4-wire serial port interface (SPI) controls all of the on-chip registers. In addition, two address pins allow SPI control of up to four devices on the same serial lines. Dedicated transmit and receive load pins also provide synchronization of all ADAR1000 chips in the same array, and a single pin controls fast switching between the transmit and receive modes. The ADAR1000 is fabricated in a silicon-germanium, bipolar CMOS (BiCMOS) process. The device is available in a compact, 88-terminal, 7 mm ? 7 mm, LGA package and is specified from ?40?C to +85?C.APPLICATIONS Phased array radar Satellite communications systems

The Texas Instruments THS1041 is a 10-bit, 40-MSPS, high-speed analog-to-digital converter (ADC). For many years because of its low power dissipation and extended life, it has been used in various applications such as programmable gain amplifier and built-in clamp. With recent FPGA development, some application systems have been upgraded with a direct interface of the THS1041 to an FPGA, for example, by connecting I/O pins of the THS1041 to the I/O pins of Xilinx™ Spartan-3 or Altera™ program logic device (PLD). For such an interface, a power-on initial state should be considered in the interface design. Otherwise, the power-on initial state of the FPGA can affect the initial state of THS1041 and in some cases, affect the entire application system. In order to ensure the successful interfacing of the THS1041 to an FPGA, a test was conducted, and this application report presents those results.
