UCC5696 用于 SPI-5 以及后代产品的仅 27 线路 LVD SCSI 终端
The UCC5696 is a 27-line LVD only SCSI programmable terminator. The nominal settings on power up are compliant to SPI–2 through SPI–4. The programmable settings are used for SPI–5. The UCC5696 uses the I2C to program the differential impedance and the differential bias current. The differential impedance is programmed in 5-
using 4 bits (16 steps). The differential bias current is programmed in 50 uA from 0.7 mA to 1.45 mA using 4 bits (16 steps). The UCC5696 has the SPI–3 mode change delay, the typical value is 200 ms.
The UCC5696 can not be used for single-ended or HVD SCSI, the termination lines will open when it detects either single-ended or HVD devices on the SCSI bus
