... MHz. In addition, the PLL circuitry will produce a 50% duty cycle square-wave clock output (see Figure 7). The NB4N507A can be programmed to generate a selection of input reference frequency multiples. An exact 155.52 MHz output clock can be generated from a 19.44 MHz crystal and the x8 multiplier selection. ...

... X1 to ground and X2 to ground. The value of these capacitors is given by the following equation, where CL is the specified crystal load capacitance: Crystal caps (pF) = (CL- So, for a crystal with 16 pF load capacitance, use two 22 pF caps, including board trace capacitance (see Figure 7). 8. Guaranteed by design and characterization. NB4N507A = 3 5.5 V, GND = -40°C to +85°C (Note 3)) DD ...

... NB4N507A, along with a low frequency fundamental mode crystal, can build a high frequency differential PECL output oscillator. For example MHz crystal connected to the NB4N507A with the 12X output selected ( produces a 120 MHz PECL output clock. Crystal Oscillator Input Interface The NB4N507A features an integrated crystal oscillator to minimize system implementation costs ...
