1. General description
The PTN3342 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 PTN3342 operates
at a 3.3 V 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 V of ground potential difference
between two LVDS nodes. The PTN3342 is identical to the PTN3332 but with the
termination resistor integrated with the receiver.
The intended application of this device is for point-to-point baseband transmission rates
over a controlled impedance media of approximately 100 Ω. The maximum rates and
distance of data transfer are dependent upon the attenuation characteristics of the media
selected and the noise coupling to the environment.
The PTN3342 is designed to function over the full industrial temperature range of
−40 °Cto+85°C.
