Ixora Datasheet

1 Introduction
Ixora is a carrier board for the Apalis family of System-on-Modules (SoMs) / Computer on modules(CoMs). Ixora is designed to provide access to some of the most important features supported by the
Apalis family.
The major part of the standard interfaces, which are supported by the Apalis modules, are exposed on
the Ixora carrier board through a combination of real-world connector interfaces, card slot and 2.54mm
pitch pin headers.
The real world connectors, LEDs, and push buttons are all placed on the board edge in a way that easily
allows for a boxed version of the Ixora carrier board.

3 Interface Description
3.1

Apalis System-On-Module

Type:

MXM3 321 pin Socket

Manufacturer: JAE - MM70-314-310B1
For the pin-out of the Apalis module, please refer to the applicable Apalis module datasheet.
MXM3 SnapLock and Spacers are available on Ixora for fixing the Apalis module with the carrier board.
Please use M3 size screws to fasten Apalis module with the Spacers.

3.2

Power Supply

3.2.1

Power Supply Connectors

Ixora provides two methods of supplying power to the board:-

The connector X2, which is a standard 5.5mm power jack barrel connector which is widely usedin consumer electronic devices.
The connector X3, which is a pluggable, dual-pin male screw type terminal block which is widelyused in industrial applications. This connector is not assembled by default.

The connectors X2 and X3 are directly connected to the power output connector X4, to the FAN connector
X6 and to the LVDS connector X19. For this reason, when the 12V voltage supply is required on theseconnectors, the input voltage must be 12V +/-10%.
Both the connectors have a wide input voltage range of 7 - 27V DC.
The on-board power supply provides the following supplies (maximum power).
5V / 6A (30W)
3.3V / 8A (26.4W)
The supply is protected against reverse input voltage polarity and short circuits.

Ixora Datasheet
3.2.2

Power Control

Power control of the Ixora is implemented using a Linear LTC2954 Pushbutton On/Off controller and withthe signal POWER_ENABLE_MOCI, which is used to enable the peripheral power supplies.
For information about the signals provided by the controller LTC2954 please refer to the datasheet. For
more information regarding the power up sequence which is implemented on the board please refer to the
document “Apalis Carrier Board Design Guide”.
The switches SW1 and SW2 have been assigned the ON/OFF and Reset function, respectively. The SW3
is, by default, connected to pin 186 of the MXM3 connector and can be used to activate particularfunctionalities such as factory default restore. By disassembling resistor R91 and assembling resistor R90,
SW3 will be routed to pin 63 which is, for the Apalis T30 module, the Recovery Mode pin.
Please note that pin 63 of the MXM3 connector can only be used to enter Recovery Mode on the Apalis
T30 and TK1 module, not on iMX6 and iMX8 modules, due to the inverted signal level.
The Power Control Header X5 allows the Reset and Power Button control signals to be accessed
externally.

USB

Ixora has 1x USB 2.0 host interface (X7), as well as a USB 2.0 OTG interface available on a Micro-AB
connector (X9).
The USB 2.0 part of the USB OTG interface is shared with the dual stacked USB 3.0 type A connector X8(bottom), which can be used with the modules that support USB Super Speed interface.
By using the jumper JP2, it is possible to determine whether the interface USBO1 is used as an OTG
interface through the connector X9 or as a Host interface available on the bottom part of the connector
X8.
The Jumper JP2 is basically used to connect the signal USBO1_ID signal to GND: the USBO1_ID signal
enables the VCC_USBO1 voltage in the same way as when the port X9 is used as HOST.
When the VCC_USBO1 is enabled, the bottom part of the connector X8 or X9 is used as HOST.
For this reason, special attention needs to be paid to this jumper when the connector X9 has to be used
as CLIENT.
In order to give an indication that the voltage VCC_USBO1 is enabled, LED3 has been installed on theboard.

By default, Apalis USBH2 and USBH3 interfaces are connected to Mini PCIe Connector (X25) and USB
Host connector (X7) respectively. Using the assembly options, it is possible to connect the USB Hostconnector (X7) and Mini PCIe Connector (X25) to connect to either the USBH2 or USBH3 interface.
Customers must pay special attention while making the assembly changes to ensure that only one USBH
interface is connected to one connector at a time.

PCIe

Ixora supports the PCI Express interface on the Apalis module and allows Mini PCIe devices to beconnected.
By changing the value of the GPIO connected to pin 176 of the MXM3 connector, it is possible to disable
the wireless capabilities of the mini PCIe card assembled in the connector X25. In particular, the wirelessis disabled when this signal voltage is zero.

Display

Ixora provides many options for connecting LCD panels and monitors, with the following three interfaces
supported:•••

18 bit digital RGB
Dual Channel 24 bit LVDS
HDMI

Not all the display interfaces are available on all Apalis modules. Carefully check the corresponding
datasheet of the module.
Toradex provides a range of different tools and utilities to help with the easy configuration of different LCD
panels. For details please refer to: http:/developer.toradex.com

3.9.1

Unified Interface Display (X15)

Ixora carrier board provides a digital RGB interface port (18-bpp) to interface with the LCD panels using
a 40-way, Unified Interface Display connector (X15). It also includes a 4-wire resistive touch screeninterface on the same FFC connector.
The Unified Interface Display connector (X15) is compatible with the Resistive Touch Display and EDT
display offered by Toradex. A variety of LCD panels with integrated touch support for evaluation purposes
are available at the Toradex Webshop.

3.10 Audio
Ixora offers one analogue audio interface, which is provided by the Apalis Module. It is available on theconnector X12. This connector is a standard jack for active loudspeakers or headphones and microphone
input. The audio jack follows the CTIA (AHJ) pinout standard. Please refer to this Wikipedia(https://en.wikipedia.org/wiki/Phone_connector_(audio)#TRRS_standards) to view the list of thecompatible headphones.
In addition, Ixora features the Line IN and S/PDIF IN and OUT interfaces on a non-assembled 7-pin

3.11 Digital and Analog I/O Interface
3.11.1 UART
Ixora features 4 UART interfaces that are connected to the following connectors:••••

UART 1 to the connector X22 through an RS232 transceiver.
UART 2 to the connector X21 through an RS232 transceiver.
UART 3 to the connector X21 through an RS232 transceiver and to the connector X27.
UART 4 to the connector X27.

It is possible to disconnect the signal UART3_RXD from the RS232 IC12 SN65C3243 transceiver by
disassembling the jumper JP3. In addition, it is possible to put the transceiver IC12 in high impedance
status by forcing to zero, the value of the GPIO connected to pin 180 of the MXM3 connector.
One of these two configurations is required when the interface UART3 need to be used at the TTL levelon the connector X27.

3.11.2 CAN
Ixora uses the Analog Devices ADM3053BRWZ signal and power CAN transceiver to implement two CAN
2.0b interfaces in conjunction with the two CAN interfaces on the Apalis module. The CAN ports areelectrically isolated from the system power supply.
On Ixora V1.2, it is possible to enable/disable CAN1 and CAN2 transceiver. MXM3_158 (MMC1_D7) and
MXM3_35 (SATA1_ACT#) can be used to enable/disable power to the CAN1 and CAN2 transceivers
respectively. Please refer to the Ixora carrier board schematics for more details.
The CAN interfaces are available on the Header X20.

3.11.5 Real-Time Clock (RTC)
External RTC
The Ixora carrier board uses the STMicroelectronics, M41T0M6 chip as external RTC. I2C1 bus(MXM3_209 and MXM3_211) RTC can be assessed the external RTC.

Battery Holder (BAT1)
A 12 mm (diameter) coin cell/battery should be used with the Battery Holder (BAT1). Coin cell can beused to provide power backup to the external RTC circuits when external power supply is not available.
The following types of batteries are supported: BR1216, CR1216, BR1220, CL1220, CR1220, BR1225.
Note:
The spring contact on the top side of the battery holder sets/bends based on the battery thickness.
In case a thicker battery (like BR1225, 2.5mm thickness) is inserted first, the spring contact will set andlater if the battery is replaced by a thinner battery (like BR1220, 2.0mm thickness), the battery holder
will not hold the replacement battery firmly.
Customers are advised to not to use a thinner battery after using the thicker battery with the battery
holder (BAT1).
