Frequency to Voltage Converter Analog Front-End Prototype
Read More >>
The device compares multiple filter circuits side-by-side.
The frequency to voltage converter analog front end evaluation prototype (F2V AFE) is an evaluation board designed for comparison of different methods of accurately extracting the frequency of a sinusoidal input signal. A configurable input stage is routed to one ...Read More >>
Dust-Tolerant Intelligent Electrical Connection System
Read More >>
This technology has application in aerospace, military, homeland security, mining, and oil and gas exploration operations that are conducted in uncontrolled environments.
Faults in wiring systems are a serious concern for the aerospace and aeronautic (commercial, military, and civilian) industries. Circuit failures and vehicle accidents have occurred and ...Read More >>
Gigabit Ethernet Asynchronous Clock Compensation FIFO
Clock compensation for Gigabit
Ethernet is necessary because the clock
recovered from the 1.25 Gb/s serial data
stream has the potential to be 200 ppm
slower or faster than the system clock.
The serial data is converted to 10-bit parallel
data at a 125 MHz rate on a clock
recovered from the ...

High-Speed, Multi-Channel Serial ADC LVDS Interface for Xilinx Virtex-5 FPGA
Analog-to-digital converters (ADCs) are used in scientific
and communications instruments on all spacecraft. As data
rates get higher, and as the transition is made from parallel
ADC designs to high-speed, serial, low-voltage differential signaling
(LVDS) designs, the need will arise to interface these in
field-programmable gate arrays (FPGAs). As Xilinx ...
