Dual 1:5 Differential Clock Drivers with LVPECL Inputs and LVDS Outputs
General Description
The MAX9317/MAX9317A/MAX9317B/MAX9317C lowskew, dual 1-to-5 differential drivers are designed for clock and data distribution. The differential input is reproduced at five LVDS outputs with a low output-tooutput skew of 5ps. The MAX9317/MAX9317A are designed for low-voltage operation from a 2.375V to 2.625V power supply for use in 2.5V systems. The MAX9317B/MAX9317C operate from a 3.0V to 3.6V power supply for use in 3.3V systems. The MAX9317A/MAX9317C feature 50Ω input termination resistors to reduce component count. The MAX9317 family is available in 32-pin 7mm ✕ 7mm TQFP and space-saving 5mm ✕ 5mm QFN packages and operate across the extended temperature range of -40°C to +85°C. The MAX9317A is pin compatible with ON Semiconductor’s MC100EP210S. o 145ps (max) Part-to-Part Skew o 5ps Output-to-Output Skew o 330ps Propagation Delay from CLK_ to Q_ o 2.375V to 2.625V Operation (MAX9317/MAX9317A) o 3.0V to 3.6V Operation (MAX9317B/MAX9317C) o ESD Protection: ±2kV (Human Body Model) o Internal 50Ω Input Termination Resistors (MAX9317A/MAX9317C)
