1. Minimum sensitivity and saturation levels at BER=1E-12 for a 2⁷-1 PRBS at ER= 9 dB. For example, an OMA of 22 µW is
approximately equal to an average power of -18.4 dBm, average with an Extinction ratio of 9 dB.
2. The current excludes the output load current.
3. These outputs are compatible with 10K, 10KH and 100K ECL and PECL outputs.
