Frequency Generator & Integrated Buffers for Celeron, PII/IIITM & K6 Processors

Recommended Application: This motherboard component serves as a single-chip clock solution for Pentium II/III and K6 processors, specifically designed for use with SIS540/SIS630 style chipsets.

Output Features:

• Supports up to 3 CPUs at 2.5/3.3V, with frequencies of up to 166MHz.
• Provides 14 SDRAM outputs at 3.3V.
• Offers 7 PCI outputs at 3.3V.
• Includes a fixed 48MHz output at 3.3V.
• Provides a selectable 24/48MHz output at 3.3V, controlled via I2C (default is 24MHz).
• Includes 2 REF outputs at 3.3V, operating at 14.318MHz.

Additional Features:

• Supports frequencies up to 166MHz.
• Supports FS0-FS3 trapping status bit for I2C readback.
• Enables power management features, allowing control of CPU, PCI, SDRAM stop, and power-down modes through I2C programming.
• Offers spread spectrum functionality for EMI control, with a range of 0 to -0.5% (±0.25%).
• Requires internal 120K pull-down resistors to GND for FS0, FS1, and FS3.
• Utilizes an external 14.318MHz crystal for operation.
