LVDS or LVTTL/LVCMOS Input to
14 LVTTL/LVCMOS Output Clock Driver
General Description
Features
The MAX9160 125MHz, 14-port LVTTL/LVCMOS clock
driver repeats the selected LVDS or LVTTL/LVCMOS
input on two output banks. Each bank consists of seven
LVTTL/LVCMOS series terminated outputs and a bank
enable. The LVDS input has a fail-safe function. The
MAX9160 has a propagation delay that can be adjusted
using an external resistor to set the bias current for an
internal delay cell. The LVTTL/LVCMOS outputs feature
200ps maximum output-to-output skew and 100ps maxi-
mum added peak-to-peak jitter.

The MAX9160 is designed to operate with a 3.3V sup-
ply voltage over the extended temperature range of
-40°C to +85°C. This device is available in 28-pin
exposed- and nonexposed-pad TSSOP and 32-lead
5mm x 5mm QFN packages.
