http://www.colognechip.de - they have got pretty nice chips.
Unfortunately, for U interface you need an external IC.

Hello folks,
I am looking for an ISDN U transceiver in 3.3V technologie. So far I've
checked Motorolas MC145572 (5V) and some Infineon parts. The older Infineon
parts are 5V too and the SMINT series are a bit of an overkill (intelligent
NT chip with U and S/T transceiver).
Does anyone know a chip with preferably the following features:
- 3.3V (1.8V would be ok too)
- Integrated HDLC Controller (B-channels or 144kB IDSL)
- Large FIFOs (say >32 bytes)
- Flexible PCM highway (GCI, IOM2, ..)
Thanks for any pointers
- Rene
