I don't know of any off-the-shelf solutions, but it could easily be
done in an FPGA.

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.

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
