This signal is asserted "High" to indicate loss of signal at the receive input. 100 26 50 76 RxPOS_0/RData_0 RxPOS_1/RData_1 RxPOS_2/RData_2 RxPOS_3/RData_3 O Receiver 1 Positive Data Output: In dual-rail mode, this signal is the receive P-rail output data. Receiver 1 NRZ Data Output: In single-rail mode, this signal is the receive output data. 99 27 49 77 RxNEG_0/LCV_0 RxNEG_1/LCV_1 RxNEG_2/LCV_2 RxNEG_3/LCV_3 O Receiver_n Negative Data Output: In dual-rail mode, n-rail data are sent to the framer. Line Code Violation Output - Channel_n: In single-rail mode, this signal output "High" for one receive clock cycle to indi- cate a code violation is detected in the received data. If AMI coding is selected, every bipolar violation received will cause this pin to go "High". 95 31 45 81 RRing_0 RRing_1 RRing_2 RRing_3 I Receiver_n Differential Negative Input. 94 32 44 82 RTIP_0 RTIP_1 RTIP_2 RTIP_3 I Receiver_n Differential Positive Input. 67 RXMUTE I Hardware Mode, Receive Muting: Connect this pin "High" to mute RxPOS/RxNEG output to a low state upon receive LOS condition to prevent data chattering. Connect Low to disable mut- ing function. TRANSMITTER SECTIONS 3 23 53 73 TxNEG_0 TxNEG_1 TxNEG_2 TxNEG_3 I Transmitter_n Negative NRZ Data Input. In dual-rail mode, this signal is the n- rail input data for transmitter 0. In single-rail mode, this pin can be left uncon- nected. 4 22 54 72 TxPOS_0/TData_0 TxPOS_1/TData_1 TxPOS_2/TData_2 TxPOS_3/TData_3 I Transmitter_n Positive Data Input. In dual-rail mode, this signal is the p-rail input data for transmitter 0. Transmitter 0 Data Input. In single-rail mode, this pin is used as the NRZ input data for transmitter 0. |
