General Information

First released on 30 April 2002, the chipset Family has had V.34 & V.32bis options from the beginning (designed for embedded applications such as POS Terminals, Set-Top Boxes, Video Recorders, Metering, Security and Remote Site Management) as well as the ‘traditional’ V.90/V.92 external dial-up modem. Flash-ROM is an option, allowing updating/customisation of the MCU firmware and MDP code modules--this is typical of all ACF modem Family types.

V.92 PCM-upstream, FastPOS (V.29) & various other added features/bugfixes (such as no longer disconnecting when switching from voice to fax mode) were introduced on 30 April 2003 within the updated masked firmware code of an updated set of chip revisions (from CX81801-3x/5x/6x to CX81801-7x/8x/9x).

All chipsets use either the 20463 SmartDAA2 (Global only) or the lead-free 20493 SmartDAA3. All chipsets are DFT with Full-Duplex Speakerphone options using a 20437 VC.

With 3 sub-types in the Family, a major chip-code revision across all chipsets, lead-free variations, et al, there are a bewilderingly-large number of possible chips within this Family of chipsets. It all boils down to a simple 2-chip chipset with Speakerphone option:

• SCM: 81801
• DAA: 20463 or 20493
• VC: 20437 (option)
