ASM3P2180A Datasheet Peak Reducing Emi Solution

Manufacturer: Alliance Semiconductor Corporation

Overview: September 2004 .. 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.
