... MC2042-4 LED/Laser Driver for FDDI, Fast Ethernet, Fibre Channel, OC3/STM-1, IEEE1394 The MC2042 CMOS IC designed for high-speed LED drive in low-cost optical fiber based transmission sys- tems. Depending on the LED used, data rates to >300 Mbps can be achieved. The LED drive current is set by a resistor. To improve LED ‘on’ time, a pre-emphasis circuit is included, which may be set via a simple RC network ...

... Pre-Emphasis Or ‘Peaking’ To improve LED ‘turn on’ time an optional pre-emphasis function is included on the MC2042-4. If this is not required, then the PEAK pin should be left floating. Two external components (R4, C1) are required as shown in Figure 4-1 to implement peaking. When the LED is turned on, the voltage on PEAK is pulled LOW very rapidly. This voltage transient is coupled through R4 and C1 and exerts a transient current on the LED ...
