Dual 1:5 Differential Clock Drivers with LVPECL
Inputs and LVDS Outputs
General Description
Features
The MAX9317/MAX9317A/MAX9317B/MAX9317C low-
skew, 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-to-
output skew of 5ps.
ꢀ Guaranteed 1.0GHz Operating Frequency
ꢀ 145ps (max) Part-to-Part Skew
ꢀ 5ps Output-to-Output Skew
ꢀ 330ps Propagation Delay from CLK_ to Q_
ꢀ 2.375V to 2.625V Operation (MAX9317/MAX9317A)
ꢀ 3.0V to 3.6V Operation (MAX9317B/MAX9317C)
ꢀ ESD Protection: 2kV (Human Body Model)
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 sys-
tems. The MAX9317A/MAX9317C feature 50Ω input ter-
mination resistors to reduce component count.
ꢀ Internal 50Ω Input Termination Resistors
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.
