7 0 Electrical Characteristics
DC Electrical Characteristics for All 100K ECL Compatible Inputs
The following signals are covered PMD Indicate Data (PMID) Receive Clock In (RXC IN) Receive Data In (RXD IN) and
Signal Detect (SD)
Note 1 Both inputs of each differential pair are tested together These specifications guarantee that the inputs are compatible with standard 100K ECL voltage
level outputs
Note 2 V
DC Electrical Characteristics for 100K ECL Compatible Outputs
The following signals are covered PMD Request Data (PMRD) and Transmit Clock (TXC)
DC Electrical Characteristics for Alternate PMD ECL Outputs
The following signals are covered Receive Clock Out (RXC OUT) and Receive Data Out (RXD OUT)
Note 3 It is recommended that RXC OUT

Supply Current Electrical Characteristics
included in the PLAYER
Since the outputs are differential the average output level is V
through the 50
As a result the termination for each pair of active ECL outputs typically consumes 30 mA time averaged
