Datasheet for Qualcomm Atheros AR8236

6-port low-power Fast Ethernet Switch

AR8236 Product Overview
The AR8236 is a fast Ethernet switch solution that offers low power, very small form factor, enhanced features and competitive RBOM. It is well-suited for broadband networking products such as xDSL routers, HomePlug powerline bridges and 5-port switches.
The AR8236 features an internal power-saving mechanism which enables automatic standby and link detection modes to meet the European Code of Conduct specification for low-power and on states. The low-power state provides 80% power saving over “on” state.
Enhanced features such as QoS, VLAN, double-tagging, hardware IGMP v1/v2/v3 and MLD 1/2 snooping features function without burdening the host processor. Hardware Looping Detection provides the system CPU with the option of using these blocks to increase performance and video quality. The AR8236 supports 9K byte jumbo frames to enable connectivity to Gigabit-enabled devices that also support jumbo frames.
AR8236 package is a 68-pin QFN, the industry's smallest package for a switch offering these features. The small package can give a customer the option of easily fitting the solution into a small housing. The device can also integrate multiple functions, such as Wi-Fi and VoIP, so that the PCB size and cost can also be reduced, while maintaining the small housing made possible by the AR8236’s compact package size.
