| 摘要 |
The present invention relates to a method and an arrangement for the prevention of metastability as an asynchronous digital signal (A) is received in a first clock domain (1), working with a first clock frequency (C1), where the received signal is transmitted from a second clock domain (2), working with a second clock frequency (C2). The second clock frequency (C2) is known within the first clock domain (1). A reference signal, with a known phase information within the first clock domain, is used in the second clock domain. The phase information is available, with a certain uncertainty, in the received signal (A). The phase information, with its uncertainty, is used to read the received signal (A) in a stable manner.
