9107C-05CS08LFT

Application Specific Clock/Timing Overview

The AV9107C-05CS08LFT is a processor-specific clock generator manufactured by Integrated Circuit Systems (ICS), now part of Renesas Electronics. It provides two simultaneous outputs: a fixed REFCLK matching the input reference frequency and a synthesized CLK1 output ranging from 2 to 120 MHz. The device utilizes a patented on-chip Phase-Locked Loop with VCO, eliminating the need for external loop filter components. It operates on a single +3.3V or +5V supply and features up to 16 preprogrammed frequencies stored in internal ROM. The 'CS08' suffix indicates an 8-pin SOIC package.

Application Specific Clock/Timing Feature Summary

• Patented on-chip PLL with integrated VCO and loop filter
• Generates CLK1 frequencies between 2 MHz and 120 MHz
• Up to 16 selectable frequencies stored in internal ROM
• Glitch-free frequency transitions during speed changes

Application Specific Clock/Timing Applications

• Computer CPU frequency scaling for power management
• Graphics applications requiring VGA standard frequencies
• Disk drive proximity oscillators
• High-speed systems requiring low jitter clocks

Application Specific Clock/Timing Procurement Notes

Verify the manufacturer lineage as ICS was acquired by Renesas. Confirm that the 'LFT' suffix denotes lead-free compliance and tape-and-reel packaging if required by assembly specifications. Ensure the design option matches the -05 variant for the specified voltage and frequency ranges.

Application Specific Clock/Timing Selection Notes

Select the AV9107C-05 variant specifically for operation at +5V (4.5V to 5.5V) where CLK1 can reach up to 120 MHz. For +3.3V operation, verify that the maximum output frequency requirement does not exceed 66.6 MHz. Ensure the input reference frequency falls within the 11 MHz to 19 MHz range typical for this option.

Application Specific Clock/Timing Part Context

This component belongs to the AV9107C family of CPU frequency generators. Other variants include the -03, -10, and -11 options, which differ in supported voltage levels and maximum output frequencies. The -05 option is optimized for standard 5V computer motherboard applications.
