UCC5696PN

The UCC5696PN 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 UCC5696PN uses the I2C to program the differential impedance and the differential bias current.The UCC5696PN has the SPI-3 mode change delay,the typical value is 200 ms.

Features of the UCC5696PN are:(1)meets Ultra2 (SPI-2 LVD SCSI),Ultra3,Ultra 160 (SPI-3),Ultra320(SPI-4),and Ultra640 (SPI-5) standards;(2)2.7-V to 5.25-V termpwr operation;(3)differential fail-safe bias;(4)I2C bus adjustable impedance and;(5)latching PWM for cyclebycycle current limiting differential bias current;(6)80-pin low profile quad flat pack package (QFP).

The absolute maximum ratings of the UCC5696PN can be summarized as:(1):the parameter is TERMPWR voltage,the rating is 6,the unit is V;(2):the parameter is signal line voltage,the rating is 0 to 6,the unit is V;(3):the parameter is package power dissipation,the rating is 1,the unit is W;(4):the parameter is operating junction temperature,TJ,the rating is -55 to 150,the unit is ;(5):the parameter is storage temperature, Tstg,the rating is -65 to 150,the unit is ;(6):the parameter is lead temperature (soldering,10 sec.),Tsol,the rating is 300,the unit is .
