General Description
The EL6201C is a solid state high performance laser modulation oscil-
lator with external resistor adjustable frequency and amplitude. The
EL6201C is available in both the 8-pin MSOP and the 5-pin SOT23, 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 ampli-
tude 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 modula-
tion 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 EL6201C has internal supply bypass capacitors to reduce oscilla-
tion noise spread through supply connections.
