active termination

active termination

[¦ak·tiv ‚tər·mə′nā·shən]
(computer science)
A means of ending a chain of peripheral devices connected to a small computer system interface (SCSI) port, suitable for longer chains, where it can reduce electrical interference.

To support DDR2, the first switching regulator can be used to generate 1.8V for memory chip supply and the second switching regulator can be used to provide a 0.9V floating reference to support the DDR2 active termination requirement.
Active termination adds voltage regulators to the resistors used in passive termination, which allow more reliable and consistent termination of the bus.
Check that there is active termination on both ends of the bus and, that all other termination is disabled.
The control panel provides immediate feedback through its backlit alphanumeric display and key pad and is used to identify which drives are active, to set the SCSI address, to initiate the hot-swapping of drives, and to regulate the active termination of the unit.
The MAX1541 powers chipsets and graphics processor cores that require dynamically adjustable output voltages, or it generates the active termination bus that tracks the input reference.
Q: We are currently using SCSI cables with active termination. Some of these cables are with twisted wires between the connectors and some of them are straighforward cables.
* Active Termination for "plug-and-play" installation and reconfiguration
The BGA design substantially reduces capacitance and lead inductance, making the device ideal for high performance active termination of SCSI networks.
Active termination uses a regulator and an 110 ohm resistor; this is a better impedance match and significantly better pull up current.
