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.
