xDSL

 * CX94410 (ADSL2+ chipset with enhanced INP)
 * CX94610 (ADSL2+ chipset with integrated WLAN)
 * CX94615 (ADSL2+ chipset with integrated WLAN)

Routers with Linux embedded

 * LevelOne WBR-3600
 * Linksys WAG54G2
 * Netgear DG834Gv5
 * Netgear MBR624GU
 * Huawei HG522 (Ezbox)

Routers with ATMOS/ISOS

 * Billion BiPAC 7402GX
 * AtlantisLand A02-RAU244-W300N
 * Belkin F5D7634NT4A v1000
 * Intertex SurfinBird IX78
 * Pirelli DRG A124G (Pirelli DRG A125G - Broadcom !!)
 * ZTE ZXV10 H608B
 * Zoom X6 5590C
 * XAVi X7968 (OpenWrt Wiki)
 * Xavi 7968 uses SoC of Conexant CX 94610-11Z which is in use for other routers, some of them already exploiting linux as OS.
 * However, the vast majority of CX 94610-11Z routers use ATMOS/ISOS firmware developed by GlobespanVirata.




 * CX94610 CPU probably uses the ARM1026EJ core (Datasheet)

Although the Solos has not PCI bus, there are some interesting peripherals:
 * SPI: for flash, VoIP slics or any other peripheral.
 * Hardware crypto engine for DES, 3DES, MD5 and SHA1.
 * USB 1.1/2.0 with gadget support (needs a ULPI interface for EHCI support).
 * 802.11 a/b/g MAC. The CX50221 and CX50321 are simple RF chips.
