1:5 Clock Driver with Selectable
LVPECL Inputs and LVDS Outputs
General Description
The MAX9310 is a fast, low-skew 1:5 differential driver
with selectable LVPECL/HSTL inputs and LVDS out-
puts, designed for clock distribution applications. This
device features an ultra-low propagation delay of 345ps
with 45.5mA of supply current.
The MAX9310 operates from a 2.375V to 2.625V power
supply for use in 2.5V systems. A 2:1 input multiplexer
is used to select one of two differential inputs. The input
selection is controlled through the CLKSEL pin. This
device also features a synchronous enable function.
The MAX9310 is offered in a space-saving 20-pin
TSSOP package and operates over the extended tem-
perature range from -40掳C to +85掳C.
