DESCRIPTION
The STLVDS32 is a differential line receiver that
implements the electrical characteristics of low
voltage differential signaling (LVDS). This
signaling technique lowers the output voltage
levels of 5V differential standard levels (such as
TIA/EIA-422B) to reduce the power, increase the
switching speeds and allow operations with a 3.3V
supply rail. This differential receiver provides a

valid logical output state with a 3.3V supply rail. It
also provides a valid logical output state with a
±100mV
differential input voltage within the input
common mode voltage range. The input common
mode voltage allows 1V of ground potential
difference between two LVDS nodes.
The intended application of this device and
signalling technique is both point-to-point and
multidrop data transmission over controlled
impedance media approximately 100Ω. The
transmission media may be printed circuit board
traces, backplanes or cables. The ultimate rate
and distance of data transfer depend upon the
attenuation characteristics of the media and noise
coupling to the environment.
The STLVDS32 version is characterized for
operation from -40°C to 85°C.

Note 1: t
sk(O)
is the maximum delay time difference between the propagation delay of one channel and that of the others on the same chip
with any event on the inputs.
Note 2: t
sk(P)
is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge
of the same channel.
Note 3: t
sk(PP)
is the differential channel-to-channel skew of any event between devices. This specification applies to devices at the same
V
CC
, and within 5°C of each other within the operating temperature range.
