FXMHD103 HDMI Voltage Translator
Description
Features
The FXMHD103 is a reduced-pin-count, low-power,
CEC, DDC, and HPD Level Shifting without a
High-Definition Multimedia Interface (HDMI), voltage
Direction Pin
translator for the Data Display Channel (DDC),
Consumer Electronic Control (CEC), and Hot Plug
Host Port Voltage Supply (V ): 1.6V 3.6V
CCA
Detect (HPD) control lines.
HDMI Port Voltage Supply (V ): 4.8V 5.3V
CCC
There are three non-inverting bi-directional voltage
Long HDMI Cable Support with Integrated DDC
translation circuits for the DDC serial data (SDA)/clock

(SCL) lines and CEC lines. Each line has a common
2
power rail (V ) on the host side from 1.6V to 3.6V. On

the HDMI connector side, the SCL_C and SDA_C pins
Pin Out Tailored for PCB Trace Routing to HDMI
each have an internal 1.75K pull-up connected to the
Type D Connectors
HDMI 5V rail, V . The SCL and SDA pins exceed the
CCC
HDMI specification for driving up to 800pF loads. The
Back Drive Protection
CEC_C pin has an internal 27K pull-up to an internal
Non-Preferential Power-Up/Down Sequencing
3.3V supply (V ).

the HDMI connector port to the host port. HPD_H
references V , and HPD_C references V . HPD_C
CCA CCC
ESD Protection:
offers hysteresis to avoid false detection due to
- 8kV HBM (per JESD22-A114)
bouncing while inserting the HDMI plug.
- 2kV CDM (per JESD22-C101)
The FXMHD103 device can be powered down if the OE
pin is LOW. If OE is HIGH, the HPD path is enabled. If
Applications
an HDMI sink asserts the HPD_C pin HIGH, the DDC
and CEC paths are enabled. OE references V .

Note:
1. The external TVS devices depicted in the Application Drawing (Figure 2) provide system-level IEC61000-4-2,
Level 4 ESD protection to the mobile device system at the HDMI connector. The FXMHD103 provides device-
level ESD protection defined in the ESD section of the Absolute Maximum Ratings table.
