1.
The AT43301 is a 5-port USB hub chip supporting one upstream and four down-
stream ports. The AT43301 connects to an upstream hub or host/root hub via Port0,
while the other ports connect to external downstream USB devices. The hub re-trans-
mits the USB differential signal between Port0 and Ports[1:4] in both directions. The
AT43301 is designed for very low-cost bus-powered or self-powered hub applications
and is available in a 24-lead SOIC and a 32-lead LQFP packages. The 32-lead ver-
sion of the AT43301, the AT43301-AC, has a 48 MHz clock input.
Description
The AT43301 supports the 12 Mb/s full speed as well as 1.5 Mb/s slow speed USB
transactions. To reduce EMI, the AT43301’s oscillator frequency is 6 MHz even
though some internal circuitry operates at 48 MHz.
