High-Density Design With MicroStar? BGAs (Rev. C)
Texas InstrumentsThe consumer electronics industry constantly faces new challenges to design their solutions smaller and less expensive. One of the industry's most limiting design factors is board real estate and its increasing cost. The cost can be thought of in purely dollar terms or more importantly can be indirectly related to the lost revenue caused by a competitive disadvantage when the competition's solut

High-Speed ADC THS1041 and FPGA Interface Considerations
Texas InstrumentsThe 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.
