4.4.9 HSIC Interface*
HSIC is a two-wire source-synchronous serial interface with a signal level of 1.2 V. It is
suitable for low-power applications with standard LV CMOS levels.
The HSIC interface is a high-speed inter-chip interconnection bus, and supports a data
transmission rate of 480 Mbps. When routing, control the routing impedance to 50Ω.
