LX5212 General Description
The LX5212 is a nine-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 LX5212 requires a meager 500nA of supply current while offering only 2.5pF 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 presents a 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 LX5212 consumes only 600µA 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 LX5212 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 LX5212 sinks up to 30mA of current, making it compatible with today's fast active negation drivers. The LX5212 is a superior, pin-for-pin replacement for a variety of industry products, such as the UC5614.
