Advance Information
Frequency Timing Generator for Peripherals
9FGP205
Recommended Application:
Peripheral Clock for Intel Servers with Wake-On-Lan support
Output Features:
• 1 - 0.7V current-mode differential CPU output
• 6 - 50MHz RMII outputs
• 2 - 125MHz RGMII outputs
• 1 - 0.7V current-mode differential DOT 96MHz output
• 1 - 33.33MHz output
• 1 - 32.768KHz output
• 2 - 25MHz REF outputs
Key Specifications:
• Exact synthesis on CPU, RGMII, RMII & 33.33MHz
clocks
• +/- 100ppm frequency accuracy on other clocks
Features/Benefits:
• Selectable SMBus Address - D0/D1 or C0/C1
• Spread Spectrum capability on CPU and DOT 96MHz
clocks
• SMBus Control:
- M/N and spread programming on CPU and DOT
96MHz clocks via SMBus
- Differential outputs can be disabled via pins or SMBus
