STM1E-SFPxx 155Mbps Copper Transceiver
Final Datasheet
Data and Control Interface
The STM1E-SFPxx data I/Os accept and provide differential signals at 155.52Mbit/s. AC-coupling for both
transmit and receive traces is handled internally and is thus not required on the host board.
The receive data outputs (RD+/-) provide the recovered STM1/STS3 data to the host in NRZ coding.
During Rx LOS of signal conditions, the receive outputs are squelched. The RD+/- traces on the host
card should be of equal length and differentially terminated with 100 ? at the user SerDes.
The transmit data inputs (TD+/-) accept STM1/STS3 NRZ data at CML or LVPECL levels. The transmit
timing is recovered inside the 78P2351R LIU and used for the CMI line encoding and transmit pulse
driver. The TD+/- traces on the host card should be of equal length.
The physical layer IC used in the STM1E-SFPxx does not require reset or software configuration. Only an
optional Transmit Disable control pin is available for enabling or powering down the transmit driver.
For status monitoring, a Receive Loss of Signal indicator is provided. Loss of Signal detection for STM-1e
(electrical) interfaces is inherently different from optical LOS detection. Reference Receiver Loss of Signal
Condition section for more info on LOS detection criteria for STM-1e (ES1) interfaces.
