Description
The PI6C48545-11 is a high-performance low-skew LVDS fanout
buffer. PI6C48545-11 features selectable single-ended clock or
crystal inputs and translates to four LVDS outputs. The CLK input
accepts LVCMOS or LVTTL signals. The outputs are synchronized
with input clock during asynchronous assertion /deassertion of
CLK_EN pin. PI6C48545-11 is ideal for crystal or LVCMOS/LVTTL
to LVDS translation. Typical clock translation and distribution ap-
plications are Data Communications and Telecommunications.
