PLL501-02/04
VCXO Clock Generator
On-chip tunable voltage-controlled crystal oscillator circuitry (VCXO) allows precise system frequency tuning (pull range 300ppm minimum). VCXO tuning range: 0-3.3V. Uses inexpensive fundamental-mode crystals. Integrated phase-locked loop (PLL) multiplies VCXO frequency higher system frequencies needed. 3.3V supply voltage. Small circuit board footprint (8-pin 0.150'' SOIC). Custom frequency selections available. 12mA output drives capability level.
