different from PATA or IDE, but SATA software protocols are backwards compatible with
PATA.
SMBus System Management (SM) Bus
A two-wire, bidirectional bus (clock and serial data) that is used for system
management such as reading parameters from a memory card and reading
temperatures and voltages of system components.
The SMBus uses the same signaling scheme as an I
Stripline A constant width internal layer PCB trace that is sandwiched between two reference
planes. If the stripline trace is equidistant between the two reference planes, it is said to
be symmetric or balanced. If the stripline trace is closer to on of the planes, it is said to
be asymmetric or unbalanced.
TMDS Transition Minimized Differential Signaling
A low voltage differential signaling scheme for flat-panel displays that is an alternative
to flat-panel LVDS. TMDS uses 8b/10b encoding to achieve DC balance and is used for
DVD-D displays
USB Universal Serial Bus
A hot-pluggable serial I/O interconnect standard.
VESA Video Electronics Standards Association
An industry trade group that issues standards for CRT and flat-panel displays.
