PIN DESCRIPTION
PIN
NAME
FUNCTION
1, 2, 11–26,
37–48
RxP, RxN
Signal Termination. Connect to SCSI bus signal lines.
3
TPWR
Termination Power. Connect to the SCSI TERMPWR line and decouple with a 2.2
F
capacitor.
4–9, 28–33
HS_GND
Heat-Sink Ground. Internally connected to the mounting pad. This should be grounded.
10
VREF
Reference Voltage. 2.85V reference in SE mode and 1.25V reference in LVD mode; must be
decoupled with a 4.7
F capacitor.
27
GND
Ground. Signal ground, 0V.
34
DIFF_CAP
DIFFSENSE Capacitor. Connect a 0.1
F capacitor for the DIFFSENSE filter. Input to detect
the type of device (differential or single-ended) on the SCSI bus.
35
DIFFSENSE
DIFFSENSE. Output to drive the SCSI bus DIFFSENS line.
36
ISO
Isolation. When pulled high, the DS2125 isolates its bus pins (RxN, RxP) from the SCSI bus.
