I want to interface use 56K modem chipset with C51/PIC MCU? Do anyone
have experience to do this?

I know one modem chipset is msm6946, but it is difficult to be bought
and the datasheet is just Japanese.

Thanks!

For production of a one-off? If it's a one-off then just buy an
external serial-port modem and use a MAX232 or similar.

So you get an external modem, and take it out of its case.

I've not looked at recent modems, but my USR Sportster 33.6K modem
is fairly small when you just look at the board.

A friend who had been buying up older USR modems for a product has
now switched to modem modules. I have no idea of what specifically, or
how fast they are, but for him they were a suitable replacement for
the external modems.
