AV9107C-17
CPU Frequency Generator
General Description
The AV9107C-17 offers a tiny footprint solution for
generating two simultaneous clocks. One clock, the
REFCLK, is a fixed output frequency which is the same as
the input reference crystal (or clock). The other clock,
CLK1, can vary between 25.06 and 33.29 MHz.
The device has advanced features which include on-chip
loop filters, tristate outputs, and power-down capability. A
mini-mum of external components - two decoupling
capacitors and an optional ferrite bead - are all that are
required for jitter-free operation.
Features
• _{Patented on-chip Phase-Locked Loop with VCO}
for clock generation
• Provides reference clock and synthesized clock
• Generates frequencies of 25 and 33 MHz
• 8-pin DIP or SOIC package
• 14.318 MHz input reference frequency
• On-chip loop filter
• Low power CMOS technology
• ^{Single +3.3 or +5 volt power supply}
Applications
Computer: The AV9107C-17 is the ideal solution for
replacing high speed oscillators and for reducing clock
speeds to save power in computers. The device provides
smooth, glitch-free frequency transitions so that the CPU
can continue to operate during slow down or speed up. The
rate of frequency change makes the AV9107C-17
compatible with all 386DX, 386SX, 486DX, 486DX2, and
486SX devices.
