450 MHz HFM Oscillator Features General Description • • • • • Small 5-pin SOT-23 package Frequency to 450 MHz typ. Amplitude to 100mA pk/pk typ. Single +3.5V to +5.0V supply Simple to use - only two external resistors required • Independent resistor setting for frequency and amplitude. The EL6200C is a solid state high performance laser modulation oscillator with external resistor adjustable frequency and amplitude. The EL6200C is available in the 5-pin SOT23 to enable device placement close to the laser for reduced EMI signature. Applications The EL6200C has internal supply bypass capacitors to reduce oscillation noise spread through supply connections. • • • • • • • • • • DVD- Players Optical disk drives DVD-ROM drives DVD-RAM drives CD-RW drives MO drives Optical pickup head assembly Laser diode modulation Local oscillator Communications lasers EL6200C - Product Brief EL6200C - Product Brief The oscillator frequency is set by connecting a single external resistor from the RFREQ pin to ground. The oscillator current output amplitude is set by connecting a single external resistor from the RAMP pin to ground.
