MAX9317/MAX9317A/MAX9317B/MAX9317C 19-2543 Rev 0 7/02 Dual 1:5 Differential Clock Drivers with LVPECL Inputs and LVDS Outputs General Description Features The MAX9317/MAX9317A/MAX9317B/MAX9317C low- Guaranteed 1.0GHz Operating Frequency skew, dual 1-to-5 differential drivers are designed for 145ps (max) Part-to-Part Skew clock and data distribution. The differential input is reproduced at five LVDS outputs with a low output-to- 5ps Output-to-Output Skew output skew of 5ps. 330ps Propagation Delay from CLK to Q The MAX9317/MAX9317A are designed for low-voltage operation from a 2.375V to 2.625V power supply for use 2.375V to 2.625V Operation (MAX9317/MAX9317A) in 2.5V systems. The MAX9317B/MAX9317C operate 3.0V to 3.6V Operation (MAX9317B/MAX9317C) from a 3.0V to 3.6V power supply for use in 3.3V sys- tems. The MAX9317A/MAX9317C feature 50 input ter- ESD Protection: 2kV (Human Body Model) mination resistors to reduce component count. Internal 50 Input Termination Resistors The MAX9317 family is available in 32-pin 7mm 7mm (MAX9317A/MAX9317C) TQFP and space-saving 5mm 5mm QFN packages and operate across the extended temperature range of -40C to +85C. The MAX9317A is pin compatible with Ordering Information ON Semiconductors MC100EP210S.
