摘要： A redriver chip is inserted between a transmitter chip and a receiver chip and re-drives differential signals from the transmitter chip to the receiver chip. The redriver chip has switched output termination that switches to a high value to detect far-end termination at the receiver chip, and to a low value for signaling. An output detector detects when the receiver chip has termination to ground and enables switched input termination to provide termination to ground on the lines back to the transmitter chip so that the far-end termination on the receiver chip is mirrored back to the transmitter chip, hiding the redriver chip. An input signal detector detects when the transmitter chip begins signaling and enables an equalizer, limiter, pre-driver, and output stage to re-drive the signals to the receiver chip. The input signal detector also causes the switched output termination to switch to the low value termination for signaling.

摘要： A frequency-multiplying circuit generates a multiple of the fundamental frequency of a crystal that oscillates. A first differential multiplier is coupled to the crystal nodes and generates a frequency-doubled output. The frequency-doubled output is applied to an op amp that buffers the output and compares it to a reference to generate a pair of differential buffered signals. The differential buffered signals are applied to a second differential multiplier that generates a final quadrupled-frequency output. The differential multipliers can each have a pair of differential transistors that receive signals that oscillate out-of-phase to each other by 180 degrees. The drains of the differential transistors connect together at a summing node to sum the transistor currents, producing the frequency-doubled output. A crystal driver circuit using cross-coupled and direct-coupled transistors may also be attached to the crystal nodes.

In such an embodiment, an input voltage is provided to a voltage converter at a first voltage level.

摘要： A re-driver circuit has pre-driver, intermediate, and output stages. Pre-emphasis on the output is generated by the intermediate stage and injected into an output stage. The intermediate stage is a frequency-tuned amplifier that has an inductive-capacitive L-C tank circuit that is tuned to a desired frequency of the output. The intermediate stage does not directly drive the output stage. Instead, an on-chip coupling transformer couples the L-C tank circuit to the output stage. The coupling transformer has a first inductor that is part of the L-C tank circuit in the intermediate stage, and a second inductor that is part of the output stage. Mutual inductance between the first inductor and the second inductor inductively couple a pre-emphasis voltage onto the output. The magnitude of the pre-emphasis can be changed by adjusting current in the intermediate stage.
