Maxim Integrated MAX9325EQI

Description
The MAX9325 is a lowskew, 2:8 differential driver that features extremely low outputtooutput skew (50ps max) and parttopart skew (225ps max). These features make the device ideal for clock and data distribution across a backplane or board. The device selects one of the two differential HSTL or LVECL/LVPECL inputs and repeats them at eight differential outputs. Outputs are compatible with LVECL and LVPECL, and can directly drive 500 terminated transmission lines.
The differential inputs can be configured to accept a singleended signal when the unused complementary input is connected to the onchip reference output voltage VBB. All inputs have internal pulldown resistors to VEE. The internal pulldowns and a failsafe circuit ensure differential low default outputs when the inputs are left open or at VEE.
The MAX9325 operates over a 2.375V to 3.8V supply range for interfacing to differential HSTL and LVPECL signals. This allows highperformance clock or data distribution in systems with a nominal 2.5V or 3.3V supply. For LVECL operation, the device operates with a 2.375V to 3.8V supply.
The MAX9325 is offered in 28lead PLCC and spacesaving 28lead QFN packages. The MAX9325 is specified for operation from 40°C to 85°C.
