STLVDS32BTR集成電路（IC）的驅動器接收器收發(fā)器規(guī)格書PDF中文資料

STLVDS32BTR屬于集成電路（IC）的驅動器接收器收發(fā)器。由意法半導體集團制造生產的STLVDS32BTR驅動器，接收器，收發(fā)器該系列產品的主要功能是提供必需的硬件資源，以通過延長電纜或印制線進行通信。確切的功能會因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對于通信用途可能并非絕對必要，但對于可能的使用環(huán)境卻是明智之選。

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 5 V differential standard levels (such as TIA/EIA-422B) to reduce the power, increase the switching speeds and allow operations with a 3.3 V supply rail. This differential receiver provides a valid logical output state with a 3.3 V supply rail. It also provides a valid logical output state with a ±100 mV differential input voltage within the input common mode voltage range. The input common mode voltage allows 1 V 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 Ω. 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 -55°C to 125°C.
