Four Output Differential Buffer for PCI Express
ICS9DB401
Recommended Application:
DB800 Version 2.0 Yellow Cover part with PCI Express
support with extended bypass mode frequency range.
Output Features:
• 4 - 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
• Extended frequency range in bypass mode:
Revision B: up to 333.33MHz
Revision C: up to 400MHz
Features/Benefits:
• Spread spectrum modulation tolerant, 0 to -0.5% down
spread and +/- 0.25% center spread
• Supports undriven differential outputs in PD# and
SRC_STOP# modes for power management.
