Note 1: Common-anode configuration refers to a configuration where POL = GND, POL = V CC , and an NPN device is used to set
the laser bias current. Common-cathode configuration refers to a configuration where POL = V CC , POL = GND, and a PNP
device is used to set the laser bias current.
Note 2: Deterministic jitter measured with a repeating K28.5 bit pattern 00111110101100000101. Deterministic jitter is the peak-to-
peak deviation from the ideal time crossings per ANSI X3.230, Annex A.
Note 3: For Fibre Channel and Gigabit Ethernet applications, the peak-to-peak random jitter is 14.1 times the RMS jitter.
Note 4: Delay from a fault on MD until FAULT is asserted high.
