PIN DESCRIPTION
PIN
NAME
FUNCTION
1
VREF
Reference Voltage. 2.85V reference in SE mode and 1.25V reference in
LVD mode; must be decoupled with a 4.7F cap.
2, 3
NC
No Connection. Do not connect these pins.
4–7, 11–16,
22–25, 29–32
RxP,
RxN
Signal Termination. Connect to SCSI bus signal lines.
8, 10, 26, 9,
28, 27
HS GND
Heat Sink Ground. Internally connected to the mounting pad. Should
be grounded.
17
ISO
Isolation. When pulled high, the DS2118M isolates its bus pins (RxP,
FxP) from the SCSI bus.
18
GND
Ground. Signal ground; 0V.
19
MSTR/SLV
Master/Slave. Mode-select for the noncontrolling terminator. When
pulled high (MSTR), the DIFFSENSE driver is enabled.
20
DIFFSENSE DIFFSENSE. Output to drive the SCSI bus DIFFSENS line.
21
DIFF_CAP
DIFFSENSE Capacitor. Connect 0.1F capacitor for DIFFSENSE
filter. Input to detect the type of device (differential or single-ended) on
the SCSI bus.
33
SE
Single-Ended. SE output of DIFFSENSE receiver; indicates SE bus
operation.
34
LVD
Low-Voltage Differential. LVD output of DIFFSENSE receiver;
indicates LVD bus operation.
35
HVD
High-Voltage Differential. HVD output of DIFFSENSE receiver;
indicates HVD bus operation or thermal shutdown.
36
TPWR
Termination Power. Connect to the SCSI TERMPWR line and
decouple with 2.2F capacitor.
