Stratix & Stratix GX I/O Standards
4–14
Stratix Device Handbook, Volume 2
PCML standard is similar to LVPECL, but PCML has a reduced voltage
swing, which allows for a faster switching time and lower power
consumption. The PCML standard uses open drain outputs and requires
a differential output signal. See
termination. Stratix and Stratix GX devices support both input and
output levels.
Additionally, Stratix GX devices support 1.5-V PCML as described in the
Stratix GX Device Handbook, Volume 1.

The HyperTransport technology I/O standard is a differential high-
speed, high-performance I/O interface standard requiring a 2.5-V V
This standard is used in applications such as high-performance
networking, telecommunications, embedded systems, consumer
electronics, and Internet connectivity devices. The HyperTransport
technology I/O standard is a point-to-point standard in which each
HyperTransport technology bus consists of two point-to-point
unidirectional links. Each link is 2 to 32 bits. The HyperTransport
technology standard does not require an input reference voltage.
However, it does require a 100-
signals at the input buffer. See
technology termination. Stratix and Stratix GX devices support both
input and output levels.
