1.0 Features
• On-chip tunable voltage-controlled crystal oscillator
circuitry (VCXO) allows precise system frequency
tuning (pull range typically 300ppm)
• Uses inexpensive fundamental-mode crystals
• Integrated phase-locked loops (PLL) multiply VCXO
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
2.0 Description
The FS6205 is a monolithic CMOS clock generator IC
designed to minimize cost and component count in digital
video/audio systems.
An on-chip voltage-controlled crystal oscillator (VCXO)
permits the reference frequency (or output frequency) to
be tuned to match other frequencies present in the sys-
tem.
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 FS6205.
