USB 2 Hub Handles OTG

Standard Microsystems' USB20H4 hub chip supports the USB 2.0 On-The-Go (OTG) Session Request Protocol (SRP) on the upstream port and can handle traffic up to 480 Mbits/s. It supports two downstream ports without local power and four with power. The USB20H4 is based on new SMSC analog PHY technology with low-power-consumption support, suiting it for bus-powered hub/flash drive/card reader combinations and other power-sensitive applications. Housed in a 10- by 10- by 1.4-mm 64-pin TQFP, the chip costs $5.50 in OEM quantities.
