+ About the AR7 Chipset The Texas Instruments AR7 device (TNETD7300) is a fully integrated single-chip Asymmetric Digital Subscriber Line (ADSL) bridge/router solution, integrating a broadband communications processor and peripherals, ADSL physical layer, ADSL line driver, USB physical layer, Ethernet physical layer and power management for use in Customer Premise Endpoint (CPE) modems for residential and small-office applications. The TNETD7300 can be used in modems ranging from simple Ethernet bridges to integrated access devices (IADs) and Residential Gateways. The TNETD7300 includes features to enhance ADSL throughput when connected to a compatible central office ADSL modem.
ADSL+ provides downstream transmission rates far beyond the 12Mb/s limit of S=1/2. Extended-Reach (ERADSL) and All Digital Loop ADSL allow 384-kb/s/128-kb/s service to be provided on loops as long as 6.4km.
These features allow the TNETD7300 to greatly surpass the downstream throughput limit of 8 Mb/s and the 5.3km reach limits generally seen in previous ADSL modems, thus granting ADSL service providers access to a larger subscriber pool without requiring replacement of the local loop infrastructure. The TNETD7300 includes a new VLYNQ™ peripheral bus extension that allows VLYNQ-enabled devices to be gluelessly interfaced to TNETD7300 for advanced applications such as voice-over-packet (VOP) telephony or ADSL-to-WLAN (802.11) bridging and interfaces such as USB 2.0 and PCI. Featuring MIPS™ 32-Bit 160-MHz Reduced Instruction Set Computer (RISC) Processor Two IEEE Std. 802.3 Ethernet Memory Access Controllers (MACs) With One External Media Independent Interface (MII) – IEEE Std. 802.1p/q support – 10-Mbit/s and 100-Mbit/s (half or full-duplex) – Hardware flow control – Address filtering (Unicast, Multicast, Broadcast, or Promiscuous Mode) One Integrated IEEE Std.
