Description
The PI6C48545 is a high-performance low-skew LVDS fanout
buffer. PI6C48545 features two selectable single-ended clock in-
puts and translate to four LVDS outputs. The CLK
inputs accept LVCMOS or LVTTL signals. The outputs are
synchronized with input clock during asynchronous assertion/
deassertion of CLK_EN pin. PI6C48545 is ideal for single-ended
LVTTL/LVCMOS to LVDS translations. Typical clock transla-
tion and distribution applications are data-communications and
telecommunications.
