Notes:
1. Average value, when transmitting modulated light @ signal timing paramters. The output power coupled into plastic fiber P_opt is measured with
a large area detector at the end of 30 cm POF fiber with a NA = 0.5, which is ideally coupled to the transmitter.
2. Average value, when signal on Tx_Data is low.
3. The electrical input signal has to fulfill following requirements: t_PWV(min) = 18.4ns t_pwv(max) = 22.3ns, t_APWD(min) = -1.3ns and t_APWD(max) = 1.3ns,
t_DDJ(max) = 0.20ns and t_UJ = 0.09ns.
4. Characterized with Avago Characterization Boards as described in the Application note “Application Note MOST circuit for Avago ODIN
Transceiver“
5. Limits for 2UI are 38.72 … 42.66ns and for 3UI are 59.06 … 63.01ns
6. Top and Base level measured at least over 10UIs
