FN7216.3
Low Power 430MHz HFM Oscillator with
Disable
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 R
FREQ
pin to ground. The
oscillator current output amplitude is set by connecting a
single external resistor from the R
AMP
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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
