KT Datasheet(PDF) – Samsung semiconductor

Just saying hello Started by MichaelaJoy Yesterday at 6: This will be my first try at USB intefacing! NS Gopikrishnan 5. If I’m reading your data sheet right, it ignores such impossible-to-decode signals, and during such times acts the same as when it hears nothing but silence. I would have missed it otherwise: My phone-set have no caller id facility.

If you press one key and then quickly press the next, you should be okay and get the second keypress as the maximum interdigit pause time is 40 ms.

Low Power Dtmf Receiver Semiconductor

To participate you need to register. In the case of MT I have to design complex ring detection circuit to automatically off-hook. You might have to just try and see. I don’t know what your transmit latency will be.


Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. There’s no way a DTMF chip could do that.
