MAX517/MAX518/MAX519 2-Wire Serial 8-Bit DACs with Rail-to-Rail Outputs _______________General Description

... multiple devices. They operate from a single 5V supply and their internal precision buffers allow the DAC outputs to swing rail-to-rail. The MAX517 is a single DAC and the MAX518/MAX519 are dual DACs. The MAX518 uses the supply voltage as the reference for both DACs. The MAX517 has a reference input ...

... This mode is the most power-saving mode of the TJA1021. Despite its extreme low current consumption, the TJA1021 can still be woken up remotely via pin LIN, or woken up locally via pin WAKE_N, or activated directly via pin SLP_N. Filters at the inputs of the receiver (LIN), of pin WAKE_N and of pin ...

UniPro protocol stack

In mobile-telephone technology, the UniPro protocol stack follows the architecture of the classical OSI Reference Model. In UniPro, the OSI Physical Layer is split into two sublayers: Layer 1 (the actual physical layer) and Layer 1.5 (the PHY Adapter layer) which abstracts from differences between alternative Layer 1 technologies. The actual physical layer is a separate specification as the various PHY options are reused in other MIPI Alliance specifications.The UniPro specification itself covers Layers 1.5, 2, 3, 4 and the DME (Device Management Entity). The Application Layer (LA) is out of scope because different uses of UniPro will require different LA protocols. The Physical Layer (L1) is covered in separate MIPI specifications in order to allow the PHY to be reused by other (less generic) protocols if needed.OSI Layers 5 (Session) and 6 (Presentation) are, where applicable, counted as part of the Application Layer.
