Rockwell RC56HCF-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 RC56HCF-PCI modem family is available in three forms:

  1. A single 205-pin BGA (Plastic Ball Grid Array) package.
  2. 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.
  3. A 2-device set in a 176-pin TQFP (PCI BIF) and a 100-pin
     PQFP (MDP).

  R6785-61   RLVDL56DPF/SP    Modem Data Pump  144-pin TQFP
  R6785-62   RLDL56DPF        Modem Data Pump  144-pin TQFP
  R6789-51   RHP56D/SP        Modem Data Pump  100-pin PQFP
  R6789-52   RHP56D           Modem Data Pump  100-pin PQFP
  R7156-11                                     205-pin BGA

  Single device models
  RC56HCF/SP-PCI = R7156-11 (data/fax/voice/FDSP) 

  Two device models, RS56D-PCI pin compatible
  RC56HCF/SP-PCI  = 11229-14 + R6785-61 (data/fax/voice/FDSP)
  RC56HCF-PCI     = 11229-14 + R6785-62 (data/fax/voice) 

  Two device models, alternate design
  RH56D/SP-PCI    = 11229-14 + R6789-51 (data/fax/voice/FDSP)
  RH56D-PCI       = 11229-14 + R6789-52 (data/fax/voice)

Have you practice a litle love today? To your loved ones perhaps? Your parrents, your spouse, your children, your neighbours, or even your enemy? Here is a short tip on how to love them - Love is patient, love is kind. It is not jealous, is not pompous, it is not inflated, it is not rude, it does not seek its own interests, it is not quick-tempered, it does not brood over injury, it does not rejoice over wrongdoing but rejoices with the truth. It bears all things, believes all things, hopes all things, endures all things. So these three remain ... faith, hope, and love; but the greatest of these is love.
