STM1E-SFPXX 155mbps copper transceiver final datasheet STM1E-SFPXX datasheet - 2 - august 2008 v2-2 data and control interface the STM1E-SFPXX data i/os accept and provide different ial 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+/-) pr ovide the recovered stm1/sts3 data to the host in nrz coding. during rx los of signal conditions, the receive output s 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+/-) ac cept stm1/sts3 nrz data at cml or lvpecl levels. the transmit timing is recovered inside the 78p2351r liu and us ed 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 re quire reset or software configuration. only an optional transmit disable control pin is available fo r enabling or powering down the transmit driver. for status monitoring, a receive loss of signal indica tor is provided. loss of signal detection for stm-1e (electrical) interfaces is inherently differ ent from optical los detection. reference receiver loss of signal condition section for more info on los detection criteria for stm-1e (es1) interfaces.

STM1E-SFPXX 155mbps copper transceiver final datasheet STM1E-SFPXX datasheet - 3 - august 2008 v2-2 serial id interface the STM1E-SFPXX supports the 2-wire serial eeprom prot ocol for the atmel at24c01 as defined by the msa. the serial interface provides access to identification in formation. the memory is organized as byte wide data words that can be addresses individually or sequentially at device address 1010000x (a0h). special design considerations fo r using STM1E-SFPXX transceivers host enclosures that use sfp devices should provide appropriate clearances between the sfp transceivers to allow room for the larger width of the 1.0/2.3 mini-coax front end. for most systems a nominal centerline-to- centerline spacing of 16.25mm (0.640) is sufficient, but preferred coax cable types and routing clearances may require additional spacing. note : to accommodate the preferred type d coax coupling and cable ty pes, the width of the nosepiece or front end was designed to exceed the msa requirements of 13.7mm (+/- 0.1). o reference inf-8074 [appendix a, table 1, designator a] for msa recommendations o reference mechanical drawings section for STM1E-SFPXX transceiver dimensions. the sfp transceiver insertion slot should be clear of nearby moldings and covers that might block convenient access to the unique latching mechanism used in the stm1e- sfpxx. a bail-style de-latch was not feasible with a coaxial network interface so a simple push button actuat or was employed. detaching the coax cable from the STM1E-SFPXX is not required for de-latching the transceiver from the host card. notes : 1. in order to secure the larger push button de -latch mechanism, the length of the bottom of the transceiver exceeds the maximum msa requirements of 2.0mm. o reference inf-8074 [appendix a, table 1, designator y] for msa recommendations o reference mechanical drawings section for STM1E-SFPXX transceiver dimensions. 2. note: double-sided board mounting is genera lly not recommended due to the limited clearance for de-latching the STM1E-SFPXX transceiver. downloaded from: http:///
