USB 2.0-HSIC PHY (Host-Device-OTG-Hub)

The INNOSILICON USB 2.0 OTG PHY is fully compliant with UTMI+ level 3 Rev 1.0 specification. Offering excellent performance combined with a die size up to 30% less than the competition, this PHY is the perfect companion to your design. The impressively small die size offers all functionality needed for a complete USB solution. HS, FS and LS support with OTG along with all required I/Os, primary and secondary ESD, self-calibrated DP/DM termination and an integrated PLL. The UTMI+ interface can be pre-configured for either a 30MHz 16-bit, or 60Mhz 8-bit data interface.

If your solution requires more than one USB port, a further size efficiency can be had by choosing a multi-port solution. The INNOSILICON USB 2.0 PHY is available in 1, 2, 3 and 4-port configurations.

To support production test with high coverage, this PHY includes BIST, loop back, and boundary scan functionality.
