FS6206 Dual-PLL Clock Generator IC AMERICAN MICROSYSTEMS, INC. April 2000 1.0 Features 2.0 * Uses inexpensive fundamental-mode crystals * Integrated phase-locked loops (PLL) multiply crystal frequency to the higher system frequencies needed * * 3.3V or 5V supply voltage available Small circuit board footprint (8-pin 0.150 SOIC) * Custom frequency selections available - contact your local AMI Sales Representative for more information Description The FS6206 is a monolithic CMOS clock generator IC designed to minimize cost and component count. An on-chip crystal oscillator generates the reference frequency and two phase-locked loops are used to generate precise output / reference frequency ratios. See Table 1 for information on the frequency ratios programmed into each version of the FS6206.
