Description
General part information
181M Series
The 181-51 generates a low EMI output clock from a clock or crystal input. The device uses IDT's proprietary mix of analog and digital Phase-Locked Loop (PLL) technology to spread the frequency spectrum of the output, thereby reducing the frequency amplitude peaks by several dB. The 181-51 offers center spread selection of +/-0.625% and +/-1.875%. Refer to the MK1714-01/02 for the widest selection of input frequencies and multipliers. IDT offers a complete line of EMI reducing clock generators. Consult us when you need to remove crystals and oscillators from your board.
