Common-cathode configuration refers to a configuration where POL = VCC, 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. ELECTRICAL CHARACTERISTICS (continued) (VCC = +3.0V to +5.5V, TA = 0°C to +70°C, unless otherwise noted. Typical values are at VCC = +3.3V, RTC = open and TA = +25°C; see Figure 1a.)
