Description

MARKING
The NB3N20XS SERIES are pure 3.3 V supply differential
Multipoint Low Voltage (M−LVDS) line Drivers and Receivers.
Devices NB3N201S and NB3N206S are TIA/EIA−899 compliant.
NB3N201S offers the Type 1 receiver threshold at 0.0 V. NB3N206S
offers the Type 2 receiver threshold at 0.1 V.
These devices have Type−1 and Type−2 receivers that detect the bus
state with as little as 50 mV of differential input voltage over a
common−mode voltage range of −1 V to 3.4 V. The Type−1 receivers
have near zero thresholds ( 50 mV) and exhibit 25 mV of differential
input voltage hysteresis to prevent output oscillations with slowly
changing signals or loss of input. Type−2 receivers include an offset
threshold to provide a detectable voltage under open−circuit, idle−bus,
and other faults conditions.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
2. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and not valid simultaneously.
If stress limits are exceeded device functional operation is not implied, damage may occur and reliability may be affected.

APPLICATION INFORMATION
Receiver Input Threshold (Failsafe)
Type 2 receivers have their differential input voltage
thresholds offset from zero volts to detect the absence of a
voltage difference. The impact to receiver output by the
offset input can be seen in Table 10 and Figure 16.
The MLVDS standard defines a type 1 and type 2 receiver.
Type 1 receivers include no provisions for failsafe and have
their differential input voltage thresholds near zero volts.

LIVE INSERTION/GLITCH−FREE POWER UP/DOWN
While the M−LVDS interface for these devices is glitch
free on power up/down, the receiver output structure is not.
Figure 17 shows the performance of the receiver output pin,
The NB3N201/206 family of products provides a
glitch−free power up/down feature that prevents the
M−LVDS outputs of the device from turning on during a
power up or power down event. This is especially important
in live insertion applications, when a device is physically
R (CHANNEL 2), as V (CHANNEL 1) is ramped. The
CC
glitch on the R pin is independent of the RE voltage. Any
complications or issues from this glitch are easily resolved
in power sequencing or system requirements that suspend
