Abstract: A two-part interface PHY configuration includes a low-voltage PHY portion configured for instantiation on an SoC device fabricated using a cutting-edge technology node, and a high-voltage PHY portion configured for instantiation on a power management device (PMD) fabricated using a high-voltage technology node. The low-voltage PHY portion includes interface control and low-voltage I/O circuitry configured to transfer outgoing 3.3V data signals to the high-voltage PHY portion at low voltage levels, and the high-voltage PHY portion includes a driver circuit that retransmits the low-voltage data signals onto a bus at the required 3.3V level. Incoming 3.3V data signals pass through an attenuator circuit before being processed using a receiver circuit provided on the low-voltage PHY portion. In USB applications, outgoing USB High Speed data signals are generated by a driver circuit provided on a low-voltage USB PHY portion.

Abstract: Memory associated with a mobile communication device, such as memory removably inserted into a memory card slot, may be accessed, in the alternative, by a mobile communication platform or by a remote USB host. A memory access module connected to the memory card slots is operative in one of two modes: a pass-through mode and a USB mode. In the pass-through mode, the memory card slots are directly connected, via switching circuits, to memory interfaces on the mobile communication platform. A USB interface on the mobile communication platform may additionally be connected, in pass-through mode, via a USB hub to a remote USB host. In the USB mode, the memory card slots are connected, via switching circuits, second memory interfaces, and a controller, to a USB hub supporting USB 3.0 transfer protocols, and accessible by a remote host.

Abstract: A rotary encoder comprising a magnet, AMR or GMR sensors and an evaluation means. The AMR or GMR sensors are arranged to generate two signals that unambiguously encode the rotary position of the magnet within a predetermined range of rotary positions and a direction of rotation of the magnet. The evaluation means is arranged to derive single-turn and multi-turn information solely from the signals. The encoder is arranged to be switched to a power saving state for a predetermined period of time, to be at least partially reactivated thereafter and to compare a current value derived from the signals with a stored previous value derived from the signals.
