180-03 - Block Diagram


Low EMI Clock Generator

The 180-03 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 180-03 offers down spread selection of -1.25% and -3.75%. 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.
