Eight Output Differential Buffer for PCI-Express
ICS9DB108
Recommended Application:
DB800 Intel Yellow Cover part with PCI-Express support.
Output Features:
• 8 - 0.7V current-mode differential output pairs
• Supports zero delay buffer mode and fanout mode
• Bandwidth programming available
Key Specifications:
• Outputs cycle-cycle jitter < 50ps
• Outputs skew: 50ps
• +/- 300ppm frequency accuracy on output clocks
Features/Benefits:
• Supports tight ppm accuracy clocks for Serial-ATA
• Spread spectrum modulation tolerant, 0 to -0.5% down
spread and +/- 0.25% center spread
• Supports undriven differential output pair in PD# and
SRC_STOP# for power management.
