Description
The FXMHD103 is a reduced-pin-count, low-power,
High-Definition Multimedia Interface (HDMI), voltage
translator for the Data Display Channel (DDC),
Consumer Electronic Control (CEC), and Hot Plug
Detect (HPD) control lines.
There are three non-inverting bi-directional voltage
translation circuits for the DDC serial data (SDA)/clock
(SCL) lines and CEC lines. Each line has a common
power rail (V_CCA) on the host side from 1.6V to 3.6V. On
the HDMI connector side, the SCL_C and SDA_C pins
each have an internal 1.75KΩ pull-up connected to the
HDMI 5V rail, V_CCC. The SCL and SDA pins exceed the
HDMI specification for driving up to 800pF loads. The
CEC_C pin has an internal 27KΩ pull-up to an internal
3.3V supply (V_REG).
The HPD_C path is uni-directional. The direction is from
the HDMI connector port to the host port. HPD_H
references V_CCA, and HPD_C references V_CCC. HPD_C
offers hysteresis to avoid false detection due to
bouncing while inserting the HDMI plug.
The FXMHD103 device can be powered down if the OE
pin is LOW. If OE is HIGH, the HPD path is enabled. If
an HDMI sink asserts the HPD_C pin HIGH, the DDC
and CEC paths are enabled. OE references V_CCA.
Back drive protection is provided on pins facing the
HDMI connector.
