Ⅶ. How does USB3300-EZK support OTG protocol?
The USB3300-EZK is an industrial temperature high-speed USB physical layer transceiver (PHY). The transceiver interfaces to the ULPI-compliant link layer via ULPI. The ULPI interface successfully reduces the UTMI+ interface from 54 pins to 12 pins using in-band signaling and status byte transfer methods between the link and PHY. The PHY design of USB3300-EZK starts with the ULPI interface. No UTMI to ULPI wrapper is used in this design, but a seamless ULPI to link interface is provided. The result is a PHY with low latency transmit and receive times.
The USB3300-EZK is designed for flexibility so host and OTG functionality can be easily added in the future without adding additional pins. The perfect combination of the ULPI interface and Microchip's proprietary technology makes the USB3300-EZK ideal for integrating high-speed USB into new designs. In addition, USB3300-EZK adopts an industry-leading small package (5mm × 5mm), and its height is less than 1mm, which provides great convenience for its application in compact spaces. Not only that, USB3300-EZK also integrates all DP and DM termination resistors and requires a minimal number of external components, further simplifying the design and production process.
