DESCRIPTION

The SS7519 multimode SCSI terminator is

both a single-ended and a low voltage

differential terminator that meets the

specification

s of SCSI Parallel Interface (SPI-4).

The SS7519 also provides backward

compatibility to the SCSI-1, SCSI-2 and

Single-Ended specification

s. The Multimode

terminator contains all

the functions required to

terminate and auto detect for SCSI devices

without hardware fluctuation. Auto-Selectable is

achieved by using voltage detection on the

DIFFSENSE signal.

The SS7519 senses the

DIFFSENSE line while sourcing the

DIFFSENSE signal with LVD levels. The

DIFFSENSE line being grounded indicates that

one or more SE devices are attached on the bus.

The SS7519 switches to the termination mode

that is appropriate for the bus based on the value

of the DIFFSENSE input voltage.

For the Single-Ended termination, the active

terminator will pull RXN to 2.85V and RXP

to a

hard ground. The SS7519 can sink 22mA

per

line as required by the SCSI specification. The

Single-Ended resistor will maintain 110Ω ± 5%.

For LVD termination, the SS7519

integrates two current sources with nine

accuracy resistor strings. This architecture yields

a 105Ω ±5% differential and 226Ω ±10%

common mode impedance. A fail-safe bias of

110mV is sustained when no drivers are

connected to the SCSI bus. If the SS7519

detects a HVD SCSI device on the bus, all the

signals will be set to a high impedance state.
