摘要
在突发式的接收模块中 ,逻辑电平的恢复和时钟数据的恢复是其关键的问题 .交流耦合需要较长的响应时间 ,所以在频率较高的突发模式的接收方案中 ,多采用直流耦合式 ,其自动门限的控制响应时间很快 .时钟恢复在接收模块中 ,最好的方式是采用即时锁定方式.
The most difficult problem in burst mode receiver would be signal logic level recovery and data and clock recovery. There are several method to recover signal logic level and data and clock. The AC coupled plan, as it needs a long response time for ATC, is placed by DC coupled plan in higher frequency which has a fast ATC. Instant locking is the best way for CDR in a burst mode receiver.
