Detailed Description
The MAX4887 triple, high-frequency switch is intended
for notebooks and monitors permitting RGB (red,
green, blue) signals to be switched from one driver to
one of two loads (1:2) or one of two sources to be con-
nected to one load (2:1). The MAX4887 provides three
SPDT high-bandwidth switches to route standard VGA
R, G, and B signals (see Table 1).
A boosted gate-drive voltage is generated by an inter-
nal charge pump to enhance the performance of the
RGB switches. The MAX4887 high-performance switch
utilizes n-channel architecture with internal high-drive
pullup from a low-noise charge pump resulting in very
low on-capacitance. The RGB switches function with
reduced performance when the charge pump is dis-
abled (V+ > 5V). The MAX4887’s global input (EN)
places all inputs/outputs in a high-impedance state,
providing rejection of all signals.
The R_, G_, and B_ analog switches are identical, and
any of the three switches can be used to route red,
green, or blue video signals. All RGB inputs/outputs are
ESD protected to ±8kV Human Body Model (HBM).
Analog Signal Levels
Analog signal inputs over the full voltage range (0 to
V+) are passed through the switch with minimal change
in on-resistance (QP = low). When QP = high, the
switches can operate within 1V of V+. The switches are
bidirectional; therefore, R_, G_, and B_ can be either
inputs or outputs.
