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 t
PLH
and t
PHL,
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 t
PHL
) and symmetrical rise
and fall times. The resulting optical waveform has minimal duty cycle
distortion (DCD). When used with the external prebias and
precharging 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.
