5010-013 Datasheet When optical PMD devices are removed from the board, the signals at their interface to the system should be keptintact, both in logicalcontentand as voltage/current levels - see Figure l. The optical transmitter accepts both "Serial Data Out" from the PHY transmitter and "Output Disable" control (not used in lOS), at P-ECLlev- els. Similarly, the optical receiver supplies "Serial Data In" to the PHY receiver and "Carrier Detect" status (here called "Link Detect") at the same P-ECLlevels. One new signal handled by the copper interface circuit is a status signal, incorporated into Link Detect, that shows that the cable is connected at both ends. It is detected by both transmitterand receiverbecause each one uses a sepa- rate twisted pair. 5010-013 on stock Note: (1) With respect to ground. Comment: Exposing the device to stresses above those listed in Absolute Maximum Ratings could cause permanent damage. The device is not maant to be operated undar conditions outside the limits described in the operational sections of tha specification. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. |
