1:5 Clock Driver with Selectable LVPECL
Inputs/Single-Ended Inputs and LVDS Outputs
General Description
The MAX9310A is a fast, low-skew 1:5 differential driver
with selectable LVPECL inputs and LVDS outputs,
designed for clock distribution applications. This device
features an ultra-low propagation delay of 340ps with
48mA of supply current.
The MAX9310A operates from a 3V to 3.6V power sup-
ply for use in 3.3V 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 features a synchronous enable function.
The MAX9310A LVPECL inputs can be driven by either
a differential or single-ended signal. A VBB reference
voltage output is provided for use with single-ended
inputs. The device can also accept differential HSTL
signals.
The MAX9310A is offered in a space-saving 20-pin
TSSOP package and operates over the extended tem-
perature range from -40°C to +85°C.
