Dual PLL Clock Generator IC
1.0 Features
• Dual phase-locked loop (PLL) device with three out-
put clock frequencies
• 3.3V supply voltage
• Small circuit board footprint (8-pin 0.150″ SOIC)
• OE/LAT pin enables/disables CLKC output
(see Table 1)
• SELC is latched on rising edge of OE/LAT input
• Custom frequency selections available - contact your
local AMI Sales Representative for more information

2.0 Description
The FS6286 is a monolithic CMOS clock generator IC
designed to minimize cost and component count in digital
video/audio systems.
All frequencies are ratiometrically derived from the crystal
oscillator frequency. The locking of all the output fre-
quencies together can eliminate unpredictable artifacts in
video systems and reduce electromagnetic interference
(EMI) due to frequency harmonic stacking.
