General Description
The SY75576L is a high-speed, fully differential 1:4 clock fanout buffer optimized to provide four identical output copies with 137fs phase jitter and maximum 50ps outputto-output skew. Designed to be used with PCI-Express applications, SY75576L accepts and outputs HCSL or LVDS logic levels.

Features
• Four differential pairs of LVDS or HCSL outputs
• Two pairs of differential inputs accept LVDS or HCSL logic levels
• 267MHz max HCSL frequency
• 100MHz max LVDS frequency
• Ultra low phase jitter:
    − 137fsrms, 200MHz (12kHz–20MHz)
    − 153fsrms, 156.25MHz (12kHz–20MHz)
    − 212fsrms, 100MHz (12kHz–20MHz)
• <2ps Total_Jitterpk-pk, 200MHz (BER = 10−12)
• 50ps output-to-output skew
• 3.3V ±5% power supply operation
• −40°C to +85°C operating temperature
• Available in 20-pin TSSOP lead-free package

Applications
• Clock distribution
• PCI-Express
• Servers
