PL520-20 Datasheet (Micrel) - Low Phase Noise VCXO

PL520-20, Low Phase Noise VCXO

PL520-20 is a VCXO IC specifically designed to pull high frequency fundamental crystals.

Its design was optimized to tolerate higher limits of inter-electrode capacitance and bonding capacitance to improve yield.

It achieves very low current into the crystal resulting in better overall stability.

PL520-20 Low Phase Noise VCXO (for 100-200MHz Fundamental Crystals) FE AT UR E S 100MHz to 200MHz Fundamental Mode Crystals Output range (no PLL): 100MHz 200MHz (3.3V).

100MHz 170MHz (2.5V).

Low Injection Power for crystal 50uW.

Complementary outputs: CMOS, PECL or LVDS.

Selectable OE Logic (enable high or enable low).

Integrated variable capacitors.

Supports 2.5V or 3.3V-Power Supply.

Available in die form.
