2 Output PCI Express* Buffer with CLKREQ# Function
Recommended Application:
• 1-to-2 Zero-delay or fanout buffer for PCI Express
Output Features:
• 2 - 0.7V current mode differential output pairs (HSCL)
Key Specifications:
• Cycle-to-cycle jitter < 35ps
• Output-to-output skew < 25 ps
Features/Benefits:
• CLKREQ# pin for outputs 1 and 4/output enable for
Express Card applications
• PLL or bypass mode/PLL can dejitter incoming clock
• Selectable PLL bandwidth/minimizes jitter peaking in
downstream PLL’s
• Spread Spectrum Compatible/tracks spreading input
clock for low EMI
• SMBus Interface/unused outputs can be disabled
