September 2004 www.DataSheet4U.com ASM3P2180A Peak Reducing EMI Solution typical narrow band signal produced by oscillators and most clock generators. Lowering EMI by increasing a signal’s bandwidth is called spread spectrum clock generation. The ASM3P2180A uses the most efficient and optimized modulation profile approved by the FCC and is implemented by using a proprietary all-digital method. Applications The ASM3P2180A is targeted towards notebook LCD displays, other displays using an LVDS interface, PC peripheral devices and embedded systems. Key Specifications Description Supply voltages Frequency range FS1=0 FS1=1 Specification VDD = 3.3V ± 5% 6 MHz ≤ Fin ≤10 MHz 18 MHz ≤ Fin ≤ 30 MHz 325 pS (max) -1.25% or –2.4% 45/55% (worst case) 5ns (maximum) rev 1.
