PTN3332
High speed differential line receiver
Rev. 01 — 07 January 2004
Product data
1. 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.
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 PTN3332 is designed to function over the full industrial temperature range of
−40 °C
to +85
°C.
