932S401EFLF集成电路（IC）的应用特定时钟/定时规格书PDF中文资料

Recommended Application:

CK410B clock for Intel-based servers

Output Features:

• 4 - 0.7V current-mode differential CPU pairs

• 5 - 0.7V current-mode differential SRC pair

• 4 - PCI (33MHz)

• 3 - PCICLK_F, (33MHz) free-running

• 1 - 48MHz

• 2 - REF, 14.318MHz

Key Specifications:

• CPU cycle-cycle jitter: < 50ps

• SRC cycle-cycle jitter: < 125ps

• PCI cycle-cycle jitter: < 500ps

• CPU output skew: < 50ps

• SRC output skew: < 250ps

• ± 300ppm frequency accuracy on all outputs except

48MHz

• ± 100ppm frequency accuracy on 48MHz

Features/Benefits:

• Supports spread spectrum modulation, 0 to -0.5

down spread

• Uses external 14.318MHz crystal and external load

capacitors for low ppm synthesis error

• CPU clocks independent of SRC/PCI clocks

• D2/D3 SMBus address
