Note 1:
“Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
Note 2:
Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except: V
OD1
and
∆V
OD1
.
Note 3:
All typicals are given for: V
CC
= +3.3V, T
A
= +25˚C.
Note 4:
The DS90LV031A is a current mode device and only functions within datasheet specifications when a resistive load is applied to the driver outputs typical
range is (90Ω to 110Ω)
Note 5:
t
SKD1
, |t
PHLD
− t
PLHD
| is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the
same channel.
Note 6:
t
SKD2
is the Differential Channel-to-Channel Skew of any event on the same device.
Note 7:
t
SKD3
, Differential Part to Part Skew, is defined as the difference between the minimum and maximum specified differential propagation delays. This speci-
fication applies to devices at the same V
CC
and within 5˚C of each other within the operating temperature range.
Note 8:
t
SKD4
, part to part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices over recommended
operating temperature and voltage ranges, and across process distribution. t
SKD4
is defined as |Max − Min| differential propagation delay.
Note 9:
Generator waveform for all tests unless otherwise specified: f = 1 MHz, Z
O
= 50Ω, t
r
≤
1 ns, and t
f
≤
1 ns.
Note 10:
ESD Ratings:
HBM (1.5 kΩ, 100 pF)
≥
6 kV
Note 11:
Output short circuit current (I
OS
) is specified as magnitude only, minus sign indicates direction only.
Note 12:
C
L
includes probe and jig capacitance.
Note 13:
All input voltages are for one channel unless otherwise specified. Other inputs are set to GND.
Note 14:
