Rockwell RH56D-PCI

Chipset data:

Conexant Systems, Inc. formerly Rockwell Semiconductor Systems, datasheet
PCI bus controllerless (HCF) modem
Linux support
2003-09-08: The beta program for the Rockwell/Conexant HCF modem driver is over.
The proprietary driver may be purchased from Linuxant. Old, no-cost beta versions
of the driver will not be supported or distributed by Linuxant.
Read their FAQ.

2002-03-06: There is a beta driver for Rockwell/Conexant HCF modems available here.
The beta drivers are more current than the official driver.

2002-02-06: The official Conexant driver will be posted here when it is released.

  The RH56D-PCI modem family is available in two forms:

  1. A 2-device set plug-compatible with Conexant's RS56-PCI
     host modem family. The two devices are the PCI Bus
     Interface in a 176-pin TQFP and MDP in a 144-pin TQFP.

  2. A 2-device set in a 176-pin TQFP (PCI BIF) and a 100-pin
     PQFP (MDP).

  Two device models, RS56-PCI pin compatible
  RCV56HCF/SP-PCI  = 11235-14 + R6785-61 (data/fax/voice/FDSP)
  RC56HCF-PCI      = 11235-14 + R6785-82 (data/fax/voice) 

  Two device models, alternate design
  RH56D/SP-PCI     = 11235-14 + R6789-51 (data/fax/voice/FDSP)
  RH56D-PCI        = 11235-14 + R6789-52 (data/fax/voice)

  Mobile (RH56LD-PCI family)
  RH56LD/SP-PCI    = 11235-21 + R6789-21 (d/f/v/TAM/cell/FDSP)
  RH56LD-PCI       = 11235-21 + R6789-22 (d/f/v/TAM/cell)
