Abstract: A system for transmission of primary and secondary data, the system comprising: a bus; a parent node coupled to the bus; and a plurality of child nodes, each coupled to the bus, wherein: the parent node is configured to periodically transmit a time domain multiplexing (TDM) cycle beacon to the bus, wherein the TDM cycle beacon signals a start of a primary data transmission interval, and wherein the primary data transmission interval is a period reserved for transmission of primary data by the parent node and the plurality of child nodes; the parent node and each of the plurality of child nodes are operable to, responsive to the TDM cycle beacon, transmit primary data for a current TDM beacon period associated with the TDM cycle beacon to the bus during the primary data transmission interval; and the parent node and the plurality of child nodes are operable to transmit secondary data to the bus during a secondary data transmission interval between an end of the primary transmission interval and transmission by

Abstract: Circuitry for aligning a phase of an output signal with a phase of an input clock signal, the circuitry being operable in one of a plurality of phase alignment modes, wherein the plurality of phase alignment modes comprises two or more of: a single step alignment mode; a multiple step alignment mode; and a random or pseudo-random step alignment mode.

Abstract: An integrated circuit comprises first and second interfaces, an internal addressable space comprising a plurality of address ranges, and a control unit. Each of the first and second interfaces is coupled to the internal addressable space via the control unit. The control unit is configurable in a first state in which the control unit is configured to allow or deny the second interface access to a subset of the plurality of address ranges of the internal addressable space.

Abstract: An integrated circuit (IC), comprising: a first input pin for receiving a first input signal; a first converter configured to convert the first input signal to a first output signal; a first gain stage configured to apply a first gain to the first output signal; gain update circuitry configured to: output a first external gain control signal to a first output pin of the IC; and subsequently output a first internal gain control signal to the first gain stage to update the first gain of the first gain stage, wherein output of the first internal gain control signal is delayed relative to output of the first external gain control signal by a first predetermined delay, the first predetermined delay to compensate for signal chain delay between the first input pin and the first gain stage, wherein the gain update circuitry comprises level detection circuitry configured to determine a signal level of the first input signal or the first output signal.
