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 t he power, increase the
switching speeds and allow operationswith a 3.3V
supply rail. This differential receiver provides a

valid logical output s tate with a 3.3V supply rail. It
also provides a valid logi cal output st ate 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 ultim ate rat e
and distance of data transfer depend upon the
attenuation characte ristics of the media and noise
coupling to the environment.
The STLVDS32 v ers ion is characterized for
operation from -4 0°C to 85°C.

SWITCHING CHARACTERISTICS (Unless otherwise noted. Typical values are referred to TA=25°C
and V

CC

=3.3V)

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.
Note2: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.
