MC10EL89DG

The MC10EL89DG from On Semiconductor is a differential fanout gate specifically engineered to drive coaxial cables. This device is particularly useful in Digital Video Broadcasting applications due to its polarity-free system where each output can function as an independent driver.

The driver boasts a gain of approximately 40 and produces output swings twice as large as a standard ECL output, with a notable 1.6 V output swing. This characteristic allows for proper termination at both ends of the coaxial cable, minimizing signal loss and maintaining the required 800 mV swing at the receiving end. The MC10EL89DG accepts standard differential ECL inputs and can operate from the Digital Video Broadcast standard -5.0 V supply.

Key electrical specifications include a propagation delay of 375 ps and output swings of 1.6 V. The device supports PECL mode with a VCC range of 4.2 V to 5.7 V (VEE = 0 V) and NECL mode with a VEE range of -4.2 V to -5.7 V (VCC = 0 V). It also features internal input pulldown resistors.

Packaged in an 8-SOIC surface mount package, the MC10EL89DG operates within a temperature range of -40°C to 85°C. It is designed for applications requiring robust coaxial cable driving capabilities.
