MAX9315 1:5 Differential LVPECL/LVECL/HSTL Clock and Data Driver

Description

The MAX9315 low-skew, 1-to-5 differential driver is designed for clock and data distribution. This device allows selection between two inputs. The selected input is reproduced at five differential outputs. The differential inputs can be adapted to accept a single-ended input by connecting the on-chip V_BB supply to one input as a reference voltage.

The MAX9315 features low output-to-output skew (20ps), making it ideal for clock and data distribution across a backplane or a board. For interfacing to differential HSTL and LVPECL signals, this device operates over a +2.375V 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, this device operates with a -2.375V to -3.8V supply.

The MAX9315 is offered in a space-saving 20-pin TSSOP package.
