PTN3341
High speed differential line driver
Rev. 01 — 18 June 2001
Objective data
1. Description
The PTN3341 is a differential line driver that implements the electrical characteristics
of Low-Voltage Differential Signaling (LVDS) that 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 PTN3341 operates
at 3.3 volt supply levels and current mode output drivers. The output drivers will
deliver a minimum of 270 mV into a 50
Ω
load when enabled.
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 PTN3341 is designed to function over the full industrial temperature range of
−40
to +85
°C.
