8 Interfaces
3.1 18/24 Bit LVDS LCD
The LVDS interface is connected to the DDI0 interface of the SoC, while the translation is made
by a DisplayPort™-to-LVDS converter. (Refer to the Realtek RTD2136R-CG, Display-
Port-to-LVDS converter datasheet.)
3.2 HDMI (High-Definition Multimedia Interface)
The default setup defines the DDI1 port as HDMI and provides the following signals:
 1 Clock pair
 3 Data pairs
 Service signals
The HDMI interface is compliant with the HDMI 1.4 specification.
3.3 Camera CSI
The LEC-BTS brings out signals for two MIPI-CSI 2.0 (serial) camera interfaces, the first with
clock and one data lane, the second with clock and up to four data lanes supporting up to 800
Mbit/s of actual pixels.
3.4 Audio (HDA)
The SoC provides an HDA controller, which communicates with internal or external CODECs
over the Intel HDA serial link. HDA signals are brought out through the I2S2 pins on the SMARC
connector and are multiplexed with LPE_I2S audio signals. When HDA is active, LPE audio is
disabled.
3.5 PCI Express (PCIe)
The CPU features four PCIe x1 ports, and the LEC-BTS module uses three of them for the PCIe
interface and one of them for the Gigabit Ethernet interface. The PCIe interface supports the
PCIe Base Specification 2.0 with a maximum signal rate of 5 GT/s and can be configured to sup-
port PCIe edge cards or Express Cards.
3.6 Gigabit Ethernet
The on-board Intel I210IT Ethernet controller uses PCIe x1 (v2.1) bus signals from the CPU to
enable 10T/100TX/1000T operation through integrated MAC, PHY, and SGMII/SerDes inter-
faces.
3.7 USB Ports
The USB interface originates from two host controllers on the CPU that provide three USB 2.0
ports and one USB 3.0 port. The two USB 2.0 ports use the USB 0-2 pins on the SMARC con-
nector, and the USB 3.0 port uses the AFB_DIFF pins on the SMARC connector.
3.8 SATA
The SATA interface provides one port through the SATA0 pins on the SMARC connector. The
interface supports 1.5Gb/s and 3.0Gb/s.
3.9 I2C Bus
The LEC-BTS provides four interfaces through the I2C bus for General Purpose, Power Man-
agement, Camera, and LCD video I2C signals with operating speeds up to 400kHz. All I2C
interfaces have 1.8V pull ups with 2.2k resistors.
NOTE: Backlight Enable, Display Enable, and PWMOUT are controlled from the BIOS setup.
