... Low power CMOS design • Available in 8-pin SOIC (Small Outline Integrated Circuit) Overview The W42C31-03 incorporates the latest advances in PLL spread spectrum frequency synthesizer techniques. By fre- quency modulating the output with a low-frequency carrier, EMI is greatly reduced. Use of this technology allows systems to pass increasingly difficult EMI testing without resorting to costly shielding or redesign ...

... For these reasons, spreading percentages between ±0.5% and ±2.5% are most common. The W42C31 features the ability to select from various spread spectrum characteristics. W42C31-03 are shown in Table 1. Other spreading character- istics are available (see separate data sheets) or can be cre- ated with a custom mask ...
