The NB3N508S is part of the PureEdge™ product family and is a high precision, low phase noise Voltage Controlled Crystal Oscillator (VCXO) and phase lock loop (PLL) that generates 216 MHz MLVDS 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. The NB3N508S is designed primarily for data and clock recovery applications within end products such as ADSL modems, set top box receivers, and telecom systems. This device is housed in 5.0 mm x 4.4 mm narrow body TSSOP 16 pin package.
