MAX4929E
HDMI 2:1 Low-Frequency Translating Switch

Detailed Description
The MAX4929E low-frequency 2:1 switch is ideal for the
low-frequency portion of HDMI/DVI switching applica-
tions. The device features three independent voltage
inputs that allow the user to match any voltage level
encountered in switching without additional compo-
nents. The V+ range is from 4.5V to 5.5V to match the
HDMI/DVI 5V requirements. CLP is set to match the
EDID EPROM from 3.3V to 5.5V. VL is connected to the
same supply as the system MCU. All pins going to the
HDMI/DVI connectors are ESD-protected to ±6kV
Human Body Model (HBM).
The MAX4929E has two enable inputs. The enable
function allows the device to operate in normal mode or
go into a high-Z state. It is possible to control two
MAX4929Es with a single control bit, creating a 4:1
equivalent switch using a minimum of external compo-
nents (see Figure 6).
Supply or signals sequencing are not required for the
MAX4929E. Supply voltages V+, VL, and CLP can be
applied in any order. Signals can be applied in any
order as well.
Analog Switch
The MAX4929E features a voltage clamp function for the
two 2:1 switch. Inputs to SCL_/SDA_ are V+ level compat-
ible. Maximum output voltages of SCLO/SDAO are
clamped to CLP. For optimum performance connect the
EDID EPROM supply voltage to CLP (see Figure 6). For
proper operation of the voltage clamp, connect
SCLO/SDAO to CLP through the pullup resistors. For
maximum output range, connect CLP to V+. The output of
the switch is connected to the EDID EPROM, voltages
from 3V to 5.5V are expected.
Logic Inputs
VL is the supply to input logic HIZ_, SEL, and HPD.
Connect VL to the same supply as the system MCU for
compatibility.
V+ is the supply to the input logic of the HPIR1 and
HPIR2 inputs.
