Wide-bandwidth switches support portable USB designs
News & Analysis  
11/10/2004   Post a comment
USB OTG will provide higher data throughput (12Mbits/s) than serial I/Os such as UART outputs, says Fairchild's Jeff Ju in the November issue of Planet Analog magazine. For aesthetic design purposes, analog switches can also be used for pin sharing between (say) USB I/Os and audio headphone outputs. By doing this sharing, bulky headphone connectors can be replaced by small serial data I/Os for even slimmer design, Ju says. All this requires — guess what — analog switch bandwidth.
