DESCRIPTION

KEY FEATURES

TheLX5120UltraMAX^TMterminatorrepresents

next-generation technology for SCSI termina-

tion applications. The low-voltage BiCMOS

architecture employed in its design offers

superior performance to older passive and

active techniques.

do not necessarily adhere to recommended

■ Ultra-Fast Response For Fast-20 SCSI

Applications

SCSI hardware design guidelines, such as the

use of improper cable lengths and imped-

ances. Frequently, this situation is not con-

trolledbytheperipheralorhostdesignerand,

when problems occur, they are the first to

be made aware of these problems. The

LX5120 architecture is much more tolerant

of marginal system integrations.

Recognizing the needs of portable and

configurable peripherals, the LX5120 has a

TTL compatible sleep/disable mode. To

enter this mode, the DIS pin must be driven

low, thereby disconnecting the LX5120 from

the SCSI bus. Quiescent current is less than

150µA in this mode.

Reduced component count is also inherent

in the LX5120 architecture. Traditional ter-

mination techniques require large stabiliza-

tion and transient protection capacitors of up

to 20µF in value and size. The LX5120

architecture does not require these compo-

nents, allowing all the cost savings associated

with inventory, board space, assembly, re-

liability, and component costs.

■ Split Disconnect For Mixing 16-Bit

(Wide) Or 8-Bit (Narrow) Buses

■ 35mhz Channel Bandwidth

■ Sleep-Mode Current Less Than 150µA

■ Hot-Swap Compatible

Linfinity's architecture employs high-speed

adaptiveelementsforeachchannel,providing

the fastest response possible. The channel

bandwidth is typically 35MHz. The LX5120

compares favorably to older linear regulator

approaches whose bandwidth's are domi-

nated by the output compensation capacitor

and are limited to the 500KHz bandwidth

region (see further discussion in the Func-

tional Description section). Linfinity's archi-

tecture also eliminates the output compen-

sation capacitor typical in earlier terminator

designs. Each is approved for use with SCSI-

1,-2,-3, ULTRA and beyond — providing the

highest performance alternative available to-

day.

■ NO External Compensation Capacitors

■ Compatible With Active Negation

Drivers

■ Superior Pin-for-Pin Replacement For

The UCC5620
