MC2042-4

LED/Laser Driver for FDDI, Fast Ethernet, Fibre Channel, OC3/STM-1, IEEE1394

The MC2042-4 is a CMOS IC designed for high-speed LED drive in low-cost optical fiber based transmission systems. 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.

To minimize the effects of temperature on LED output power, LED drive temperature compensation can be set by resistor over a 500 - 10,000 ppm/°C range.

Differential positive-ECL PECL data on the input pins can be shaped, if desired, by the differential voltage on the Pulse Width Adjust PWA pins. This adjustment is continuous over a ±500 ps range. In addition, the VREF output pin allows single-ended input to the MC2042 and provides compatibility with industry-standard FO modules.

Absolute Maximum Ratings

These are the absolute maximum ratings at or beyond which the IC can be expected to fail or be damaged. Reliable operation at these extremes for any length of time is not implied.

Note The package bottom must be adequately grounded to ensure correct thermal and electrical performance, and it is recommended that vias are inserted through to a lower ground plane.
