  • Patent number: 9197403
    Abstract: An electronic device has a calibration arrangement for controlling a frequency characteristic of a PLL circuit having a phase comparator having an output for generating a phase difference signal, a voltage controlled oscillator and a divider. The divisor of the divider is programmable, and the oscillator is also directly modulated by an oscillator modulation signal. A modulation unit has a modulation input for receiving a modulation signal and generates the oscillator modulation signal and the divisor such that modulation generates a predefined change of the output frequency and a change of the divisor proportional to said predefined change. The calibration arrangement receives the phase difference signal, and has a ripple detector for providing a detector output signal by detecting a ripple on the phase difference signal correlated to edges in the modulation signal. A calibration control unit adjusts the oscillator modulation signal based on the detector output signal such that the ripple is reduced.

  • Patent number: 9197394
    Abstract: Versatility and flexibility of integrated circuits can be accomplished by remote control via a serial interface, such as SPI. Read/write accesses to the SPI slave node can be achieved according to SPI protocol by the master node. Additionally, a state machine associated to the slave node SPI needs a local clock to exercise the control of the analog functions following a write access. The serial protocol defines a serial data word transfer to comprise a number of reserved clock cycles that are not assigned for communicating a data bit value of the data word. The slave device comprises a clock unit coupled to the serial clock line for providing a derived clock based on reserved clock cycles. The derived clock is used internally in the slave device to perform internal synchronous operations.

  • Patent number: 9196576
    Abstract: A semiconductor device has a die mounted on a die paddle that is elevated above and thermally connected via tie bars to a heat sink structure. Heat generated by the die flows from the die to the die paddle to the tie bars to the heat sink structure and then to either the external environment or to an external heat sink. By elevating the die/paddle sub-assembly above the heat sink structure, the packaged device is less susceptible to delamination between the die and die attach adhesive and/or the die attach adhesive and the die paddle. An optional heat sink ring can surround the die paddle.

  • Patent number: 9195625
    Abstract: A data processing device includes an interconnect controller operable to manage the communication of information between modules of the data processing device via an interconnect. In response to a transaction request the interconnect controller selects a tag value from a set of available tag values, assigns the tag to the transaction and reserves the tag value so that it is unavailable for assignment to other transactions. If an expected response to the transaction request is not received within a designated amount of time, the transaction enters a timed-out state and the interconnect controller locks the tag value, so that it remains unavailable for assignment to other transactions until an unlock event, such as a request from software.
