Product Description

The PI6C48533-01 is a high-performance low-skew LVPECL fanout buffer. PI6C48533-01 features two selectable differential inputs and translates to four LVPECL ultra-low jitter outputs.
The inputs can also be configured to single-ended with external resistor bias circuit. The CLK input accepts LPECL or LVDS or LVHSTL or SSTL or HCSL signals, and PCLK input accepts LVPECL or SSTL or CML signals.
The outputs are synchronized with input clock during asynchronous assertion/deassertion of CLK_EN pin. PI6C48533-01 is ideal for differential to LVPECL translations and/or LVPECL clock distribution. Typical clock translation and distribution applications are data-communications and telecommunications.
