LX5208 General Description
The LX5208 is an eighteen-line active terminator for the SCSI parallel bus. This SCSI standard recommends active termination at both ends of the SCSI bus.
During disconnect mode, the LX5208 requires a meager 60µA of supply current while offering only 3.5pF of output capacitance To enter this low-power mode, the disconnect pin can be left open (floating) or driven high, thereby disconnecting the terminating resistors and placing the internal low dropout regulator into low-power mode. In disconnect mode, each termination line presentsa high impedance to the SCSI bus with the overall effect being to preserve high signal integrity and yield subsequent reliable, error free communications.
During normal operation, the LX5208 consumes only 800µA of current, which is the lowest enabled supply current of any terminator available on the market today Linfinity's proprietary BiCMOS low dropout regulator architecture enables this unique and very efficient operating characteristic.
The LX5208 also offers a precisely trimmed channel output current specified to a 5% tolerance. The maximum value of the output current is trimmed as closely as possible to the SCSI standard maximum specification to give the highest possible noise margin for fast SCSI operation. And the LX5208 sinks up to 200mA of current making it compatible with today's fast active negation drivers.
The LX5208 is a superior, pin-for-pin replacement for a variety of industry products such as the UC5601, UC5602, UC5608, and UC5609.
