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 crystal oscillator operates at the third overtone of the crystal's fundamental frequency. A value of a shunt resistor between the two phase-shift leg nodes is chosen so that the absolute value of the product gm×(Xc1)×(Xc2) is greater than the effective reactance of the crystal, where gm is the gain of the amplifier attached to the phase-shift legs, and Xc1 and Xc2 are the effective capacitive reactances of phase-shift legs at nodes X1 and X2. The third overtone is doubled by a multiplier and the final output filtered to remove the third overtone and select a frequency six times the fundamental frequency. A pair of Colpitts or Pierce amplifier half circuits is attached to the phase-shift leg nodes. The leg nodes can be capacitively isolated from Pierce-amplifier circuit nodes to improve start-up. Frequency doubling can be performed by summing currents from the two oscillator half circuits.

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.
