Apparatus and method for data strobe and timing variation detection of an SDRAM interface |
摘要 |
An apparatus for data strobe and timing variation detection of an SDRAM interface includes a differential-signal to single-end signal converter, a first phase delay circuit, a data latch circuit. The differential-signal to single-end signal converter receives a differential data strobe signal from the SDRAM interface and converts the signal into a single-end data strobe signal. The first phase delay circuit is connected to the differential-signal to single-end signal converter to delay the phase of the single-end data strobe signal for producing a delayed data strobe signal. The data latch circuit is connected to the phase delay circuit to latch synchronous data from the SDRAM interface according to the delayed single-end data strobe signal. |
