CTT - EIA/JEDEC Standard JESD8-4
The CTT I/O standard is used for backplanes and memory bus interfaces.
The CTT standard defines the DC interface parameters for digital circuits
operating from 2.5- and 3.3-V power supplies. The CTT standard does not
require special circuitry to interface with LVTTL or LVCMOS devices
when the CTT driver is not terminated. The CTT standard requires a 1.5-V

SSTL-3 Class I & II - EIA/JEDEC Standard JESD8-8
The SSTL-3 I/O standard is a 3.3-V memory bus standard used for
applications such as high-speed SDRAM interfaces. This standard
defines the input and output specifications for devices that operate in the
SSTL-3 logic switching range of 0.0 to 3.3 V. The SSTL-3 standard specifies
an input voltage range of – 0.3 V V
