| Abstract: | The key technology of burst mode receiver in passive optical networks which is a prospective access networks for FTTH, is described. A dummy transimpedance amplifier is applied to eliminate the quiescent voltage ripple in the first amplifying stage, so as to have a more stable characteristics. Especially, the technology of burst mode receiver with a self_adaptive threshold setting circuit which is very important for receiving burst mode signal, is described in detail. Also a special delay_lock_loop(DLL) is used to perform data synchronization in the first bit, so to achieve data and clock recovery. As a reference, we present out our test data here, together with designing consideration and development process. This receiver will surely satisfy APON requirement. |
