DESCRIPTION The STLVDS3486, 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 ORDERING CODES

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 100. 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 STLVDS3486 version is characterized for operation from -40C to 85C.

Note 1: tsk(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: tsk(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: tsk(PP) is the differential channel-to-channel skew of any event between devices. This specification applies to devices at the same VCC, and within 5C of each other within the operating temperature range.
