100310
Low Skew 2:8 Differential Clock Driver
General Description
The 100310 is a low skew a·bit differential clock driver which is designed to select between two separate differen· tial clock inputs. The low output to output skew « 50 ps) is maintained for either clock input. A LOW on the select pin (SEL) selects CLKINA. CLKINA and a HIGH on the SEl pin selects the CLKINS. ClKINS inputs.
The 100310 is ideal for those applications that need the ability to freely select between two clocks. or to maintain the ability to switch to an alternate or backup clock should a problem arise with the primary clock source.
A Vss output is provided for single-ended operation.
