摘要： A ring oscillator with a plurality of delay stages having selectable active loads for selecting an R-C time constant that defines a delay through the delay stage. The ring oscillator oscillation frequency is a function of the selected R-C time constant, a selectable bias level, and the number of delay stages in the ring oscillator. In one embodiment, a MOSFET device gate-to-source capacitance is used with at least one selectable resistive device to form the R-C time constant. In an alternate embodiment, a plurality of parallel coupled resistive devices and parallel coupled capacitive devices are selectively coupled to the active load circuit to set the delay through the delay stage. The resistive devices are formed to be one of a resistor configured MOSFET device and a traditional resistive element. The capacitive devices are formed to be one of a capacitor configure MOSFET device and a traditional capacitive element.

摘要： A transmit line driver with selectable slew rates and a common mode idle state comprises a capacitor array of selectable capacitors coupled between a line driver and a pre-driver wherein a slew rate may be selected by the selectable capacitors. A common mode idle state is provided by coupling a selectable switch (MOSFET in the described embodiment) to a mirror device that provides a bias current to the pre-driver wherein, when the bias current is removed by the switch, the pre-driver produces an output signal that is equal to the supply voltage for the circuit. Accordingly, a differential pair of the line driver are both biased on and provide a common mode idle state. The common mode idle state is equal to one half of an output signal magnitude for a logic one.

摘要： An analog front-end having built-in equalization includes a control module and a tunable gain stage. The control module is operably coupled to provide a frequency response setting based on a channel response of a channel providing high-speed serial data to the analog front-end. The tunable gain stage includes a frequency dependent load and an amplifier input section. The frequency dependent load is adjusted based on the frequency response setting. The amplifier input section is operably coupled to the frequency dependent load and receives the high-speed serial data. In conjunction with the frequency dependent load, the amplifier input section amplifies and equalizes the high-speed serial data to produce an amplified and equalized serial data.

摘要： A Transmit line driver with selectable pre-emphasis and driver signal magnitudes comprises a primary current driver for setting a primary current level and a pre-emphasis current driver that provides an additional amount of current that is superimposed with or added to the primary current level produced by the primary current driver. The pre-emphasis current has either negative or positive magnitude based upon a pre-emphasis signal logic state. A first current selection module defines a reference signal that is used to select the primary current driver output signal magnitude in a first current mirror, while a second current selection module is used to define a second reference signal that selects a pre-emphasis current driver signal magnitude in a second current mirror. Logic generates a binary signal to both the first and second current selection modules to select the current levels as well as the pre-emphasis signal.

摘要： The present disclosure is generally directed to a method and apparatus to communicate data between two or more semiconductor devices. In an embodiment, a method includes synchronizing a master device with a slave device, where the master device includes a semiconductor device. Synchronizing includes transmitting a first synchronization marker data pattern via a first serial interface from the master device at a first time, and receiving a second synchronization marker data pattern via a second serial interface at the master device at a second time in response to transmitting the first synchronization marker data pattern. Synchronizing also includes determining, based at least in part on the first time and the second time, a third time when a reply is to be received by the master device in response to a request transmitted from the master device to the slave device.
