3.2.1.3 Secondary Display (HDMI interface) signals
The NXP i.MX 8M processor has an HD Display Transmitter Controller (HDMI TX), which provides a HDMI standard interface for HDMI 2.0a compliant displays.
Supports HDCP 2.2 and HDCP 1.4
The signals are:
HDMI_D0+/HDMI_D0-: HDMI Output Differential Pair #0
HDMI_D1+/HDMI_D1-: HDMI Output Differential Pair #1
HDMI_D2+/HDMI_D2-: HDMI Output Differential Pair #2
HDMI_CK+/HDMI_CK-: HDMI Differential Clock
HDMI_HPD: Hot Plug Detect Input signal. +1.8V_S electrical level signal
HDMI_CTRL_CK: DDC Clock line for HDMI panel. Bidirectional signal, +1.8V_S electrical level with a 100kΩ pull-up resistor
HDMI_CTRL_DAT: DDC Data line for HDMI panel. Bidirectional signal, +1.8V_S electrical level with a 100kΩ pull-up resistor
Since HDMI Tx module is embedded in the i.MX 8 processors it is not necessary to implement voltage level shifter for TMDS differential pairs on the Carrier board. It
is still necessary, however, to implement voltage level shifters on Control data/Clock signals, as well as for Hot Plug Detect signal.
3.2.1.4 Serial Cameras
There are two MIPI-CSI2 interfaces available. The CSI0 interface supports two lanes, the CSI1 interface supports 4 lanes.
CSI0_CK+/CSI0_CK-: 2-lane CSI Input Clock Differential Pair
CSI0_RX0+/CSI0_RX0-: 2-lane CSI Input Differential Pair 0
CSI0_RX1+/CSI0_RX1-: 2-lane CSI Input Differential Pair 1
CSI1_CK+/CSI1_CK-: 4-lane CSI Input Clock Differential Pair
CSI1_RX0+/CSI1_RX0- 4-lane CSI Input Differential Pair 0
CSI1_RX1+/CSI1_RX1-: 4-lane CSI Input Differential Pair 1
CSI1_RX2+/CSI1_RX2-: 4-lane CSI Input Differential Pair 2
CSI1_RX3+/CSI1_RX3-: 4-lane CSI Input Differential Pair 3
