Term Definition
RJ45 Registered Jack 45 – an 8-pin jack used for 10/100 and GbE LAN
connections.
PLL Phase Locked Loop
RGB Red Green Blue – color components in a VGA or TFT flat-panel display.
RSVD Reserved. Pins marked RSVD should be left as no-connects.
SATA Serial AT Attachment device – a high-speed, serial-interconnect
standard for hard disks. SATA is electrically quite different from PATA or
IDE, but SATA software protocols are backward compatible with PATA.
SDVO Serialized Digital Video Out. An Intel-defined format for bringing
serialized digital video out on a high speed differential interface. SDVO
signals are electrically compatible with PCI Express and are multiplexed
with PCI Express x16 graphics signals on current Intel chipsets such as
the 915G and the 945G. SDVO signals are routed to third party encoder
chips from vendors such as Silicon Image.
Smart Battery A standard describing a uniform software and hardware interface
between a host computer system and a battery subsystem (the “Smart
Battery”) including charger electronics. Communication is over the SM
Bus.
SM Bus System Management (SM) Bus. A two wire bidirectional bus (clock and
serial data) used for system management such as reading parameters
from a memory card, and reading temperatures and voltages of system
components.
The SM Bus uses the same signaling scheme as an I2C bus.
SO-DIMM Small Outline Dual In-line Memory Module – a memory socket format
defined by JEDEC. The format is suitable for small form factor mobile
computer systems.
STN Super Twisted Nematic – a passive, flat-panel display technology that
yields very low power consumption displays. TFT displays are usually
crisper and brighter than STN, but some situations call for the lower
power consumption that STN can offer. STN displays are usually lower
resolution (up to 640 x 480) monochrome displays.
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.
Super I/O An integrated circuit that combines common PC I/O functions such as
serial ports, floppy disk controllers, parallel ports, and PS2 keyboard and
mouse.
The Super I/O system interface is typically thru the LPC (Low Pin Count)
bus. PCI-based Super I/Os also are available.
TFT Thin Film Transistor – a reference to a type of flat-panel display with an
active transistor at each pixel.
