MAX9312, MAX9314 Dual 1:5 Differential LVPECL/LVECL/HSTL Clock and Data Drivers

Description

The MAX9312/MAX9314 are low skew, dual 1-to-5 differential drivers designed for clock and data distribution. These devices accept two inputs. Each input is reproduced at five differential outputs. The differential inputs can be adapted to accept single-ended inputs by connecting the on-chip V_BB supply to one input as a reference voltage.

The MAX9312/MAX9314 feature low part-to-part skew (30ps) and output-to-output skew (12ps), making them ideal for clock and data distribution across a backplane or a board. For interfacing to differential HSTL and LVPECL signals, these devices operate over a +2.25V to +3.8V supply range, allowing high-performance clock or data distribution in systems with a nominal +2.5V or +3.3V supply. For differential LVECL operation, these devices operate from a -2.25V to -3.8V supply.

The MAX9312 features an on-chip V_BB reference output of 1.425V below the positive supply voltage. The MAX9314 offers an on-chip V_BB reference output of 1.32V below the positive supply voltage.

Both devices are offered in space-saving, 32-pin 5mm x 5mm TQFP, 5mm x 5mm QFN, and industry-standard 32-pin 7mm x 7mm TQFP packages.
