MAX9320/MAX9320A 19-2201 Rev 3 11/04 1:2 Differential LVPECL/LVECL/HSTL Clock and Data Drivers General Description Features The MAX9320/MAX9320A are low-skew, 1-to-2 differen- Improved Second Source of the MC10LVEP11 tial drivers designed for clock and data distribution. The (MAX9320) input is reproduced at two differential outputs. The dif- +2.25V to +3.8V Differential HSTL/LVPECL ferential input can be adapted to accept single-ended inputs by applying an external reference voltage. Operation -2.25V to -3.8V LVECL Operation The MAX9320/MAX9320A feature ultra-low propagation delay (208ps), part-to-part skew (20ps), and output-to- Low 22mA (typ) Supply Current output skew (6ps) with 30mA maximum supply current, 20ps (typ) Part-to-Part Skew making these devices ideal for clock distribution. For 6ps (typ) Output-to-Output Skew interfacing to differential HSTL and LVPECL signals, these devices operate over a +2.25V to +3.8V supply 208ps (typ) Propagation Delay range, allowing high-performance clock or data distrib- Minimum 300mV Output at 3GHz ution in systems with a nominal +2.5V or +3.3V supply. For differential LVECL operation, these devices operate Outputs Low for Open Input from a -2.25V to -3.8V supply. ESD Protection >2kV (Human Body Model) The pinout is the only difference between the MAX9320 Available in Thermally Enhanced Exposed-Pad and MAX9320A. Multiple pinouts are provided to simplify SO Package routing across a backplane to either side of a double- sided board. These devices are offered in space-saving 8-pin SOT23, MAX, and SO packages.
