DESCRIPTION

The 74F5300 is a LED driver designed for use in fiber optic links. The 74F5300 is ideally suited for use in high speed optical high transmitter systems. The TTL input buffer accepts TTL data. A logic high on the enable pin enables the buffer to drive the output driver amplifier. The linearizing circuits ensures a constant propagation delay for tPLH and tPHL, and controls the rise and fall times. The output driver amplifier is capable of sourcing more than 160mA and sinking more than 160mA at low impedances. The high current output driver has been designed to deal with transmission line effects of high speed switching systems with fast rising and falling edges. The performance of the system can be enhanced by matching impedance at the output for proper termination. It exhibits closely matched propagation delays (t PLH and tPHL ) and symmetrical rise and fall times. The resulting optical waveform has minimal duty cycle distortion (DCD). When used with the external pre–bias and pre–charging circuits, the response can be tailored to a specific LED to eliminate any overshoot and to minimize the long fall response. Additionally, this part can be used as the transmitter in a complete fiber optic system when combined with any of the NE5210/5211/5212 preamplifiers and NE5214/5217 postamplifiers for the optical receiver. Please refer to applications note AN1121 in the Philips Semiconductors Fiber Optic Communication Data Book for more specific applications information.
