hi, greetings, I am doing a project using ADSP TS 101s EZ-Lite board. The problem is like this: I have some data between 0 and 1, and I will output these data to the linkport on this board. I want to find a device that convert this data to a PWM generator as the duty cycle input. Any input is highly appreciated. thanks paul

As it happens, I have recently developed a TS20x link port interface in a Xilinx Spartan 3 device (much better than the one in their app note), and in a different project, I built a 63-channel PWM generator, also in a Spartan 3. It wouldn't take me very long at all to adapt and marry these together on a Xilinx eval board of some sort for you. Contact me off-list if interested. -- Dave Tweed
