    摘要: One embodiment provides an integrated circuit including a first circuit and a second circuit. The first circuit is configured to obtain a sample of a first clock via a second clock and provide a selected clock from multiple clocks based on the sample. The second circuit is configured to provide a first pointer clock based on the first clock and a second pointer clock based on the selected clock. An edge of the second pointer clock relative to an edge of the first pointer clock is limited to an uncertainty range of within one-half a first pointer clock cycle.

    摘要: A NOR gate pair includes a first and second NOR gate, each with a plurality of inputs and an output. A first NAND gate has a first input coupled to the output of the first NOR gate, a second input coupled to the output of the second NOR gate through a first input inverter, and an output. A second NAND gate has a first input coupled to the output of the second NOR gate, a second input coupled to the output of the first NOR gate through a second input inverter, and an output. A first output inverter is coupled to the output of the first NAND gate and a second output inverter is coupled to the output of the second NAND gate. This configuration assures that NOR gates used in a one-hot-decode decoder will all have logic-low outputs during a precharge phase.

    摘要: An output buffer with improved tolerance to overvoltage conditions. Among other features, especially when in a high-impedance state, the output buffer prevents a leakage path from a pad (108) through a pull-up driver (101) to supply voltage VDD when any voltage above VDD is placed on the pad (108). Further, the output buffer provides improved transient response characteristics. In one embodiment, the output buffer includes a pull-up driver (101), a first tracking transistor (120), a second tracking transistor (122), a voltage bias generator (112), and a coupling capacitor (124).

    摘要: A latch device is provided with a driver and a shadow latch. The driver has an input to accept a binary driver input signal, an input to accept a clock signal, and an input to accept a shadow-Q signal. The driver has an output to supply a binary Q signal equal to the inverse of the driver input signal, in response to the driver input signal, the shadow-Q signal, and the clock signal. The shadow latch has an input to accept the driver input signal, and an input to accept the clock signal. The shadow latch has an output to supply the shadow-Q signal equal to the inverted Q signal, in response to the driver input signal and clock signal.

    摘要: A clock signal can be synthesized by performing a clock and data recovery (CDR) operation on a potentially noisy clock source signal which has a known transition density. The CDR operation produces a desired clock signal in response to the clock source signal. In order to reduce crosstalk between plesiochronous receive and transmit clock domains of a serial data transceiver, a single common PLL is used both to recover the receive clock from the received data and to synthesize the transmit clock from a potentially noisy transmit clock source signal.
