Looking for caller id chip
Looking for caller id chip
(OP)
I am looking for a current chip to do caller id. I have tried to find some but have found them to be obsolete or unavailable. I am not an electrical enginner, so plase keep phrasing very layman-like.
Where can I get the chip, and how much should I expect it to cost?
Thanks.

TDK semiconductor makes a number of modem chips that incorporate the caller ID modem standard as well as some of the other functions needed.

Thanks.

There may well have been chips made that specifically incorporate this modem function and a microcontroller the parse the data as well as LCD display drivers making a complete system on a chip. Decoding an output from such a chip, if you can get it, may be very difficult. It is easier to use a modem chip and a serial port from a microcontroller that also controls your display or other interfaces.

US Bid shows over nearly 1/2 million MC145447's available for sale, there was even a single lot of 4 pieces.

If this is too expensive, you'll need to try and find some from other part makers:
Philips
TDK
Holtek
Novatek
Winbond
Elan Microelectronics
etc.

RE: Looking for caller id chip
I understand that buying chips in low quantities like 1 or 2 will make the chips more expensive, but doesn't $7.50 - $12.00 a chip sound too expensive? I can buy a phone with caller id for $10. Why should a single caller-id chip cost so much?
Can I buy a single chip from US Bid for only $7.50 - $12.00? I thought their minimum purchase was $500.00.
Thanks.

Why not ask around and see if you can get a couple of those for free to hack up?
