Electrical, Mechanical, and Thermal Specification
Glossary-3
Intel PXA270 Processor
Glossary
wireless carrier and providing interference-free calls for the user. Several versions of the standard are still under
development. CDMA should increase network capacity for wireless carriers and improve the quality of wireless
messaging. CDMA is an alternative to GSM.
CDPD
: Cellular Digital Packet Data Telecommunications companies can use DCPD to transfer data on unused
cellular networks to other users. IF one section, or “cell” of the network is overtaxed, DCPD automatically allows
for the reallocation of services.
Cellular:
Technology that senses analog or digital transmissions from transmitters that have areas of coverage
called cells. As a user of a cellular phone moves between transmitters from one cell to another, the users’ call
travels from transmitter to transmitter uninterrupted.
Circuit Switched
: Used by wireless carriers, this method lets a user connect to a network or the Internet by dialing
in, such as with a traditional phone line. Circuit switched connections are typically slower and less reliable than
packet-switched networks, but are currently the primary method of network access for wireless users in the U.S.
CF
: Compact Flash memory and I/O card interface
Characteristics:
Those qualities of a USB device that are unchangeable; for example, the device class is a device
characteristic.
Client:
Software resident on the host that interacts with the USB System Software to arrange data transfer between
a function and the host. The client is often the data provider and consumer for transferred data.
CML:
Current mode logic
Configuring Software:
Software resident on the host software that is responsible for configuring a USB device.
This may be a system configuration or software specific to the device.
Control Endpoint
: A pair of device endpoints with the same endpoint number that are used by a control pipe.
Control endpoints transfer data in both directions and, therefore, use both endpoint directions of a device address
and endpoint number combination. Thus, each control endpoint consumes two endpoint addresses.
Control Pipe:
Same as a message pipe.
Control Transfer:
One of the four USB transfer types. Control transfers support configuration/command/status
type communications between client and function. See also
transfer type
.
CRC:
See Cyclic Redundancy Check.
CSP:
Chip Scale Package.
CTE:
Coefficient of thermal expansion
CTI:
Computer Telephony Integration.
Cyclic Redundancy Check
(CRC): A check performed on data to see if an error has occurred in transmitting,
reading, or writing the data. The result of a CRC is typically stored or transmitted with the checked data. The stored
or transmitted result is compared to a CRC calculated for the data to determine if an error has occurred.
D-cache
: Data cache
DECT
: the Digital European Cordless Telecommunications standard
Default Address:
An address defined by the USB Specification and used by a USB device when it is first powered
or reset. The default address is 00H.
