8:1 Differential-to-3.3V or 2.5V
LVPECL/ECL Clock Multiplexer
853S058
DATA SHEET
General Description
The 853S058 is an 8:1 Differential-to-3.3V or 2.5V LVPECL / ECL
Clock Multiplexer which can operate up to 2.5 GHz. The 853S058
has 8 differential selectable clock inputs. The PCLK, nPCLK input
pairs can accept LVPECL, LVDS, SSTL or CML levels. The fully
differential architecture and low propagation delay make it ideal for
use in clock distribution circuits. The select pins have internal
pulldown resistors. The SEL2 pin is the most significant bit and the
binary number applied to the select pins will select the same
numbered data input (i.e., 000 selects PCLK0, nPCLK0).
