The BCM63381UKMMLG combines an ADSL2+ transceiver and analog front end (AFE) with a high-performance MIPS32 CPU, a 10/100 Ethernet interface, and a USB 1.1 interface into a single high-performance, costeffective monolithic device. The ADSL2+ transceiver delivers 29 Mbps downstream and 3 Mbps upstream, dual-latency framing, and embedded operations channels for remote management of the customer premises equipment (CPE).
The 280DMIPS CMT™ CPU and supplied software control the ADSL2+ modem, perform wire-speed bridging and routing between the wide area network (WAN) and local area network (LAN) interfaces, and support custom application development with industry-standard EJTAG debuggers, toolchains, and development environments.
