描述 Description

The PTN3332 is a differential line receiver that implements the electrical characteristics of Low-Voltage Differential Signaling (LVDS). This device meets or exceeds the requirements of the ANSI TIA/EIA-644 Standard. LVDS is used to achieve higher data rates on commonly used media. LVDS overcomes the limitations of achievable slew rates and EMI restrictions of previous differential signaling techniques. The PTN3332 operates at a 3.3 volt supply level. Any of the four differential receivers 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 range allows 1 volt of ground potential difference between two LVDS nodes.
