1.0 Features
• On-board crystal oscillator
• Phase-locked loop (PLL) synthesizes desired CLK
frequency
• Internal loop filter
• Internal crystal oscillator load capacitance (16pF
nominal)
• Only external components required are decoupling
capacitors
• Minimal board footprint (8-pin 0.150" SOIC package)
2.0 Description
The FS6118 is a monolithic CMOS frequency synthesizer
IC designed for cost sensitive or space limited applica-
tions.
An on-board crystal oscillator accepts a quartz crystal
and provides a different, synthesized frequency on the
CLK output. The device is packaged in an 8-pin SOIC
package for a minimal board footprint.
Custom factory-programmed clock frequencies are avail-
able. Please contact your local AMI sales representative
for more information.
