摘要
The forward error correction based clock and data recovery system according to the invention comprises a data latch (16) for intermediately storing received data, which is triggered by a sampling clock (sclk). The system further comprises an error determination unit (20, 21) for determining whether and which of the sampled received data is wrong, and for generating out of it a phase/frequency correction signal (ctrl). Furthermore, the system comprises a clock generator (23, 24, 25) for generating the sampling clock (sclk) depending on the correction signal (ctrl).
