STLVDS32B

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 at 200 MHz Low voltage TTL (LVTTL) logic output levels Pin compatible with the AM26LS32, SN65LVD32 Open circuit fail safe ESD protection: 7 kV receiver pins 3 kV all pins vs gnd 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. SOP TSSOP 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 Table 1.
