N2 - This paper presents the spread spectrum clock generator which reduces EMI. The proposed spread spectrum clock generator consists of a basic PLL, a voltage-controlled oscillator (VCO) controller, the frequency modulator, and voltage reference. The output clock frequency of the proposed clock generator is 10- phase 270 MHz and 162 MHz frequency is also supported. A phase noise of the proposed clock generator is -67.5 dBc/Hz at 45 kHz in 270MHz mode and -72 dBc/Hz at 30 kHz in 162MHz mode. 8.75dBm of the peak reduction and 0.5% of spread ratio achieved.
