Abstract

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.
