资料介绍
SCSI (Small Computer Interface) is a bi-directional parallel periph-
eral bus used in computer systems of all sizes. It is used for
computer interface with peripherals such as printers, scanners,
magnetic disks, and tape drives. Since its inception, the SCSI bus
has grown from 8 to 32 bits, and data rates have risen from 1MHz
to 20MHz and upward. Its major benefit is that it allows new
peripherals to be added to a computer with no hardware changes.

Passive Termination
Microchip Technology, Inc. 1. The termination of each signal shall consist of 220.(±5%)
to the TERMPWR line, and 330 (±5%) to ground. Using
resistors with ±1% tolerance improves noise margins.
