FN7216.1
Low Power 430MHz HFM Oscillator
w/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-pin MSOP and the 5-pin 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 products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is 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-020B.
