Notes:
(1)Condition when pin 19 OCASET is connected to ground.
(2)Time for optical power to reach 90% of its mean level following negation of Tx_Disable.
(3)Time for optical power to reach 10% of its mean level following assertion of Tx_Disable.
(4)Data input voltage (Vpin21 – Vpin22) > 300 mV, ENA (pin 1) connected to VCC, DIS (pin 2) connected to ground. RMODSET = 5.5 kΩ,
resistance to ground at GNDA = 0.35 Ω.
