FS6385 Triple PLL Clock Generator IC 1.0 Features 2.0 * Triple phase-locked loop (PLL) device with three output clock frequencies * 3.3V supply voltage * Small circuit board footprint (8-pin 0.150 SOIC) * Custom frequency selections available - contact your local AMI Sales Representative for more information Figure 1: Pin Configuration 1 VSS 2 XIN 3 XOUT FS6385 CLKA 4 8 SEL 7 VDD 6 CLKC 5 Description The FS6385 is a monolithic CMOS clock generator IC designed to minimize cost and component count in digital video/audio systems. Three high-resolution phase-locked loops generate three output clocks (CLKA, CLKB and CLKC) through an array of post-dividers. All frequencies are ratiometrically derived from the crystal oscillator frequency. The locking of all the output frequencies together can eliminate unpredictable artifacts in video systems and reduce electromagnetic interference (EMI) due to frequency harmonic stacking.
