Description
The PI6C48543 is a high-performance low-skew LVDS fanout
buffer. PI6C48543 features two selectable differential inputs and
translates to four LVDS outputs. The inputs can also be confi gured
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. PI6C48543 is ideal for
differential to LVDS translations and/or LVDS clock distribution.
Typical clock translation and distribution applications are data-
communications and telecommunications.
