What are PLDs?

PLDs or programmable logic devices refer to a variety of logic chips that are programmable at the user's site. Programmability of logic means that new chip designs can be tested and easily changed without incurring the huge photomask costs for chips completed in a fab. In addition, memory-based PLDs can be reprogrammed over and over, which allows working products to be upgraded at the user's site.

2007-05-04	High-speed ADC THS1041and FPGA interface considerations The THS1041 from Texas Instruments is a 10bit, 40MSPS, high-speed 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 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.
