Two-Lane and Four-Lane DisplayPort Passive
Switches with Separate AUX/HPD Control
General Description
The MAX4998/MAX14998 high-speed passive switches
route DisplayPort™ between two possible destinations
or vice versa in laptops or desktop PCs. The MAX4998/
MAX14998 are intended to be used where ultra-high-
speed performance and minimal input capacitance is
required.
The MAX4998 has three double-pole/double-throw
(DPDT) switches and one single-pole/double-throw
(SPDT) switch. Two DPDT switches are for high-frequen-
cy switching, one DPDT switch is for AUX, and the one
SPDT switch is for HPD. The two high-frequency switches
are selected by SEL1, and the AUX and HPD are selected
by SEL2. This part is suitable for two-lane DisplayPort
switching.
The MAX14998 has six double-pole/double-throw (DPDT)
switches. Four DPDT switches are for high-frequency
switching, and two DPDT switches are for AUX and HPD.
The four high-frequency switches are selected by SEL1,
and the AUX and HPD are selected by SEL2. This part is
suitable for four-lane DisplayPort switching.
The MAX4998/MAX14998 are fully specified to operate
from a single +3.3V (typ) power supply. The MAX4998
is available in a 3.5mm x 5.5mm, 28-pin TQFN package
with exposed pad, and the MAX14998 is available in a
3.5mm x 9mm, 42-pin TQFN package with exposed pad.
Both devices operate over the -40NC to +85NC extended
temperature range.
