The LX5245/5246/5247 ICs are Low Volt-

age Differential (LVD) Terminators de-

signed to comply with the LVD termination

specification in the SPI-2 document. The

LX5245/5246/5247 are designed specifically

for LVD applications. Because the LX5245/

5246/5247 support only LVD, they have lower

output capacitance than multimode termina-

tors such as the LX5240.

Linfinity’s UltraMAX Technology which

delivers the ultimate in SCSI bus performance

while saving component cost and board area.

Elimination of the external capacitors also

mitigates the need for a lengthy capacitor

selection process. The individual high band-

width drivers also maximize channel sepa-

ration and reduces channel-to-channel noise

and cross talk.

UltraMAX architecture insures ULTRA-2 per-

formance, while providing a clear migration

path to ULTRA-3 and beyond.

Enabled,

(DIFFSENSE) Pin Supplies A Voltage

Between 1.2V And 1.4V. In application,

the terminator DIFFSENSE output is con-

nected to the system DIFFSENSE line. If

there are no single ended or HVD devices

attached to the system the LVD output will

be enabled. If the DIFFSENSE line is LOW,

indicating a single ended device, the LX5245/

5246/5247 output will be HiZ.

DIFFSENSE line is HIGH, indicating a high

voltage differential device the LX5245/5246/

5247 output will be HiZ.

Compatible DISCONNECT Pin. The

LX5245/47 is active LOW and the LX5246

is active HIGH. During sleep mode, power

dissipation is reduced to a meager 5µA, while

also placing all outputs in a HI Z state. Also

during sleep mode, the DIFFSENSE function

is disabled and is placed in a HI Z state.
