outputs and any resistive terminations. See Figure 7 for recommended termination.

2. Measured over the range 4 MHz to 2 GHz.

and with a 2500 MBd, 8B10B serial encoded data pattern.

4. Inter-channel Skew is defined for the condition of equal amplitude, zero ps skew input signals. Input power at –10 dBm.

5. Rise and Fall Times are measured between the 20% and 80% levels using a 500 MHz square wave signal.

6. The Signal Detect output will change from logic “0” (Low) to “1” (High) within the specified assert time for a step transition in optical input power

from the de-asserted condition to the specified asserted optical power level on all 12 channels.

7. The Signal Detect output will change from logic “1” (High) to “0” (Low) within the specified de-assert time for a step transition in optical input

power from the specified asserted optical power level to the de-asserted condition on any 1 channel.
