PTN3342

High speed differential line receiver

Rev. 01 — 05 January 2004

Product data

1. 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 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.

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 °C to +85 °C.
