EL6270C - Product Brief  
Laser Driver with Ocillator and APC  
Features  
General Description  
• Low output noise = 4.0nA/rt-Hz  
• High-performance laser diode  
driver  
The EL6270C is a high-performance single channel laser diode power  
regulator and oscillator for a grounded cathode laser diode and photo-  
diode system. The EL6270C’s APC (Automatic Power Controller) will  
set the average laser diode input current for a desired average photo-  
diode output current. The APC can provide up to 100 mA of DC  
current.  
• Pin compatible with EL6257  
• Voltage-controlled output current  
source to 150 mA per channel,  
requiring one external set resistor  
per channel  
• Current-controlled output current  
source to 150 mA per channel  
• Rise time = 1.0 ns  
• Fall time = 1.1 ns  
• On chip oscillator with frequency  
and amplitude control by use of  
external resistors to ground  
An on-chip programable oscillator is provided to allow current modu-  
lation of the output laser current. Two external resistors control of  
amplitude and frequency. The Oscillator can provide up to 100mA  
pk/pk.  
A disable function is included which reduces supply current to less  
than 5µA.  
Connection Diagram  
• Oscillator to 500 MHz  
• Oscillator to 100 mA pk/pk  
• Single +5V supply (±10%)  
• Disable feature for power-up  
protection and power savings  
• TTL/CMOS control signals
