Configuration devices in a module. In some embodiments a radio-frequency module includes a serial bus including a first serial data line and a second serial data line. The radio-frequency module also includes a control component coupled to the serial bus and the first switch, the control component configured to determine whether first data is detected on the first serial data line, determine whether second data is detected on the second serial data line, and decode a command based on the first data and second data when the first data is detected on the first serial data line and when the second data is detected on the second serial data line.

Systems and methods related to configuring devices in a module

According to some implementations, a radio-frequency (RF) device includes a communication interface coupled to a serial bus. The RF device also includes a monitoring component coupled to the communication interface, the monitoring component configured to monitor the serial bus for first data transmitted to a first device coupled to the serial bus and configure the RF device based on the first data.

Devices and methods for monitoring a serial bus

Low noise serial interfaces with gated clock are provided herein. In certain configurations herein, a slave device of a serial interface includes a shift register for serially shifting in an interface data signal based on timing of an interface clock signal, a control circuit (for instance, a finite-state machine) for controlling the slave device, and a register bank for storing data programmed to the slave device via the serial interface. The control circuit cuts off or gates the interface clock signal in response to determining that an interface command received over the serial interface is not intended for the slave device.

Low noise serial interfaces with gated clock

Configuring devices in a module

A power amplifier module can include one or more switches, a coupler module, input signal pins, and a controller having first and second output terminals. The input signal pins can receive a voltage input/output signal, a clock input signal, and a data input signal. The controller can (i) set a mode of the one or more switches using a synchronous communication protocol in which the controller outputs a synchronous clock signal on the first output terminal and a data signal on the second output terminal, when the power amplifier module is in a first operating mode, or (ii) set a mode of the coupler module using an asynchronous communication protocol in which the controller outputs a first asynchronous control signal on the first output terminal and a second asynchronous control signal on the second output terminal, when the power amplifier module is in a second operating mode.

Circuits, devices, and methods for monitoring a serial bus

A simplified serial interface for a communications device. The serial interface includes an RF front end and a transmit block and at least one receive block located on different dies. The receive block is activated by a clock generator that is separate than the system clock. The at least one receive block can inhibit transmission of an enable signal to the receive block and inhibit operation of an oscillator of the interface.

Internal serial interface

Apparatus and methods for serial interfaces are provided. In one embodiment, an integrated circuit operable to communicate over a serial interface is provided. The integrated circuit includes analog circuitry, registers for controlling the operation of the analog circuitry, and a distributed slave device including a primary block and a secondary block. The registers are accessible over the serial interface using a shared register address space. Additionally, the primary block is electrically connected to the serial interface and to a first portion of the registers and the secondary block is electrically connected to the primary block and to a second portion of the registers.
