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
