STLVDS32BDR STMicroelectronics

STLVDS32B High speed differential line receivers Features Meets or exceeds the requirements of ansi TIA/EIA-644 standard Operates with a single 3.3 V supply Designed for signaling rate up to 400 Mbps Differential input thresholds 100 mV max Typical propagation delay time of 2.5 ns Power dissipation 60 mW typical per receiver SOP TSSOP at 200 MHz Low voltage TTL (LVTTL) logic output levels Pin compatible with the AM26LS32, SN65LVD32 Open circuit fail safe ESD protection: input common mode voltage allows 1 V of ground 7 kV receiver pins potential difference between two LVDS nodes. 3 kV all pins vs gnd The intended application of this device and signalling technique is both point-to-point and Description multidrop data transmission over controlled impedance media approximately 100 . The The STLVDS32 is a differential line receiver that transmission media may be printed circuit board implements the electrical characteristics of low traces, backplanes or cables. The ultimate rate voltage differential signaling (LVDS). This and distance of data transfer depend upon the signaling technique lowers the output voltage attenuation characteristics of the media and noise levels of 5 V differential standard levels (such as coupling to the environment. TIA/EIA-422B) to reduce the power, increase the switching speeds and allow operations with a The STLVDS32 version is characterized for 3.3 V supply rail. This differential receiver operation from -55C to 125C. 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 Table 1.
