Broadcom BCM421x

Chipset data:

Manufacturer

Broadcom, datasheets:

• BCM4211
• BCM4413

Applications

PCI bus soft (HSP) modem

Identifiers

Identified versions:

• BCM4210 - HomePNA (added circuitry for modem)
• BCM4211 - HomePNA + V.90 soft modem
• BCM4212 - V.90/V.92 soft modem only(?)
  These are the Gateway "Palmer" modems. This may be a custom chipset for Gateway.
• BCM4413 - HomePNA + V.90 soft modem + 10/100 Ethernet

The BCM4212 chipset resembles the PCTel 1789 chipset.
