The coupling capacitor should be 0.1μF or larger. Refer
to Application Note HFAN-1.1:
Choosing AC-Coupling
Capacitors
for a more detailed discussion.
Status Monitor
The MAX3901/MAX3902 include a status monitor
(Figure 4). The average current at the FILT (Figure 5)
pad determines whether the MAX3901/MAX3902 are in
operating or standby mode. STATUS is TTL low when
the receiver is in operating mode. STATUS is TTL high
when the receiver is in standby mode.
Applications Information
Optical Power Relations
Many of the MAX3901/MAX3902 specifications relate to
the input signal amplitude. Figure 6 and Table 1 show
relations that are helpful for converting optical power to
input signal when designing with the MAX3901/
MAX3902.
Wire Bonding
For high-current density and reliable operation, the
MAX3901 and MAX3902 use gold metalization. For
best results, use gold-wire ball-bonding techniques.
Use caution if attempting wedge bonding. Bond-pad
size is 94.4μm x 94.4μm, and bond-pad metal thick-
ness is 1.2μm. Refer to Maxim Application Note, HFAN-
08.0.1:
Understanding Bonding Coordinates and
Physical Die Size
