描述
The 8S58035I is a high-speed 2-to-6 Differential-to-LVPECL fanout buffer. The 8S58035I is optimized for high-speed and very low output skew, making it suitable for use in demanding applications such as SONET, 1 Gigabit and 10 Gigabit Ethernet, and Fiber Channel. The internally terminated differential inputs and VREF_AC pins allow other differential signal families such as LVDS, LVDS, and CML to be easily interfaced to the input with minimal use of external components. The device also has a 2:1 MUX input, allowing for easy selection between two clock reference sources. The 8S58035I is packaged in a small 5mm x 5mm 32-pin VFQFN package which makes it ideal for use in space-constrained applications.
