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.
ETSI Math Operations in C for the TMS320C62x (Rev. A)
Texas InstrumentsMany standard vocoders follow the European Telecommunications Standards Institute (ETSI) for all math operations. One of the purposes of the ETSI math functions is to standardize all math operations into a set of function calls that can be reused by many different vocoders now and in the future.The Global Systems for Mobile Communications (GSM) standard requires vocoders that follow the ETSI s

Providing Continuous Gate Drive Using a Charge Pump
Texas InstrumentsCertain applications require that output voltage regulation be maintained when the input voltage is only slightly higher than the output voltage. For a buck converter these low headroom operating conditions require high duty cycle operation that may approach 100%. As the converter on-time duration approaches the switching period the charge on the BOOT capacitor must be maintained in order for th
