EL6201C - Product Brief
Low Power 430 MHz HFM Oscillator w/Disable
Features
* Small SOT-23 and MSOP-8 packages * Frequency to 430MHz min. * Amplitude to 25mAP-P min. * Output tristate function (MSOP-8) * Power-down function (MSOP-8) * Single +3.5V to +5.0V supply * Simple to use - only two external resistors required * Independent resistor setting for frequency and amplitude.
General Description
The EL6201C is a solid state high performance laser modulation oscillator 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 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 EL6201C has internal supply bypass capacitors to reduce oscillation noise spread through supply connections.
Applications
