Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX9322 low-skew 1:15 differential clock driver reproduces or divides one of two differential input clocks at 15 differential outputs. An input multiplexer selects from one of two input clocks with input switching frequency in exc ss of 1.0GHz. The 15 outputs are arranged in four banks with 2, 3, 4, and 6 outputs, respectively. Each output bank of MAX9322 is individually programmable to provide a divide-by-1 or divide-by-2 frequency function.

The MAX9322 operates in LVPECL systems with a +2.375V to +3.8V supply or in LVECL systems with a -2.375V to -3.8V supply. A V_BB reference output provides compatibility with single-ended clock input signals and a master reset input provides a simultaneous reset on all outputs.

The MAX9322 is available in 52-pin TQFP and 68-pin QFN packages and is specified for operation over -40°C to +85°C. For 1:10 clock drivers, refer to the MAX9311/MAX9313 data sheet. For 1:5 clock drivers, refer to the MAX9316 data sheet .
