Abstract: Described are on-die termination (ODT) systems and methods that facilitate high-speed communication between a driver die and a receiver die interconnected via one or more signal transmission lines. An ODT control system in accordance with one embodiment calibrates and maintains termination resistances and drive currents to produce optimal output swing voltages. Comparison circuitry employed to calibrate the reference resistance is also used to calibrate the drive current. Termination elements in some embodiments are divided into two adjustable resistive portions, both of which are designed to minimize capacitive loading. One portion is optimized to produce a relatively high range of adjustment, while the other is optimized for fine-tuning and glitch-free switching.

CPC classification number: G06F1/12
Abstract: A source-synchronous communication system in which a first integrated circuit (IC) conveys a data signal and concomitant strobe signal to a second IC. One or both ICs support hysteresis for the strobe channel that allows the second IC to distinguish between strobe preambles and noise, and thus prevent the false triggering of data capture. Hysteresis may also be employed to quickly settle the strobe channel to an inactive level after receipt of a strobe postamble.
Abstract translation: 一种源同步通信系统，其中第一集成电路（IC）向第二IC传送数据信号和伴随选通信号。 一个或两个IC支持选通通道的滞后，允许第二IC区分选通前导和噪声，从而防止数据捕获的错误触发。 还可以采用迟滞来在接收到选通后同步码之后快速地将频闪通道置于非活动状态。
