Description
The NB3N508S is a high precision, low phase noise Voltage Controlled Crystal Oscillator (VCXO) and phase lock loop (PLL) that generates 216 MHz M−LVDS output from a 27 MHz crystal. The ±100 ppm output pullable range is obtained using the VIN pin of the VCXO with usable range from 0 V to 3.3 V. The VCXO input pin VIN is a high−impedance input that can be driven directly from a pulse width modulated RC integrator circuit.
