AC 7 - two chip 16 port ADSL infratructure chipset

Source: product bulletin

TI's AC 7 chipset is a two chip 16 port ADSL infratructure chipset. It consists of the TNETD7160 16 port multi-service ADSL Transceiver and the TNETD7122 (POTS) and TNETD7123 (ISDN) Dual Channel Analog Front End (AFE), respectively.

TNETD7160 16 port multi-service ADSL Transceiver The TNETD7160 embeds an ARM7 processor for all real-time modem operation and maintenance (OAM) control, extensively uses TI programmable DSP capability for transceiver training and steady-state functions, and includes all necessary program, data, interleaver memory, and interprocessor communications paths to reduce bill-of-materials costs. Each modem port can be configured dynamically to support ADSL, ADSL2, ADSL2+ (up to 24 Mbps), extended reach and enhanced upstream (up to 3.5 Mbps) with the same software load. Features Single chip integrates all digital functions for 16 Asymmetric Digital Subscriber Line (ADSL) ATU-C modems including digital section of the codec function Supports: 16 ADSL modems ANSI T1.413, Issue 2 ITU-T G.992.1 G.dmt (with s=1/2) ITU-T G.992.2 G.lite ITU-T G.992.3 G.dmt.bis (ADSL2 Annexes A, B, C) ITU-T G.992.3 (Annex I, J) Enhanced Upstream ITU-T G.992.3 (Annex L) Extended Reach ITU-T G.992.4 G.lite.bis ITU-T G.992.5 (ADSL2+ Annexes A, B, C) ITU-T G.992.5 (Annex L) Enhanced Upstream ITU-T G.994.1 G.hs ITU-T G.997.1 G.ploam ADSL2 Packet transfer mode (PTM) Data interfaces include: UTOPIA 2 Packet over Sonet (POS-PHY) High-Speed Serial Data Distribution Port (LVDS) Optional in-band management eliminates need for local microcontroller Glueless interface to TNETD7122 and TNETD7123 dual channel AFE line interface On chip: ARM processor and memory Interleaving memory compliant to all ANSI and ITU standards Two bit error rate tester (BERT) modules OAM register interface compatible with AC5 and AC6 TNETD7122 (POTS) and TNETD7123 (ISDN) Dual Channel Analog Front End (AFE) The TNETD7122, used in plain old telephone service (POTS), and TNETD7123, used in integrated services digital network (ISDN) implementations, are dual low-power differential ADSL central-office (CO) front ends containing line driver/receiver, codec, analog filters and hybrid used in conjunction with the TNETD7160. These devices feature active-termination drivers. The transmitter and receiver have full-bandwidth access, allowing for SELT/DELT capability and line characterization. The selectable integrated hybrid optimizes performance over different loop impedances. Features Designed for use with TNETD7160 Integrates codec functionality to reduce chip count 750-mW power for normal operating conditions Low-power dual-channel zero-overhead Class-G design ±5-V power rails Active termination differential driver/receiver Bypassable filters allow full bandwidth access for SELT/DELT Programmable integrated hybrid for enhanced upstream performance Multiple power-saving modes to support L0 L3 ITU specifications
