Product Description

The PI6C485352 is a high-performance low-skew LVPECL fanout buffer. PI6C485352 features two selectable differential inputs and translates to twelve LVPECL output pairs. The inputs can also be configured to single-ended with external resistor bias circuit. The CLK input accepts LVPECL, LVDS, LVHSTL, SSTL or HCSL signals. The PI6C485352 is ideal for differential to LVPECL translations and/or LVPECL clock distribution.

Typical clock translation and distribution applications are data-communications and telecommunications.
