Description
The EL6201 is a solid state high performance laser modulation oscillator with external resistor adjustable frequency and amplitude. The EL6201 is available in both the 8 Ld MSOP and the 5 Ld SOT-23, to enable device placement close to the laser for reduced EMI.
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. The oscillator in the MSOP package also contains a high speed output disable function using the OE pin. The OE pin can be driven by a high speed timing signal to control precise laser modulation during read/write operations. The output current is disabled when a logical zero 'L' is driven to the CE pin. Supply current is reduced to microamps when CE = LOW.
The EL6201 has internal supply bypass capacitors to reduce oscillation noise spread through supply connections.
