MCIMX53SMD Board Hardware User’s Guide, Rev. 0
Freescale Semiconductor
(both can be purchased from Freescale). The single LVDS connector will support video formats up to 165
Megapixels per second. The power source for the LVDS module is a switchable output of the VBUCKPERI DCDC
converter. This rail is shared with the SATA module and the USB module. If these modules are not used, the
PMIC can be programmed to turn off power to these three modules, without affecting the 2.5V supplies to
other portions of the i.MX53 processor.
3.10.
Ethernet (on Debug Board)
The i.MX53 processor Fast Ethernet Module outputs RMII formatted signals to an external Ethernet PHY. The
processor is capable of 10/100 Base-T speeds. The MCIMX53SMD board uses the SMSC LAN8720A Ethernet
Transceiver in a QFN-24 package. The Ethernet IC is powered by a 3.3V supply from DCDC_3V3_BB. The output
of the Ethernet PHY is connected to the debug board.
3.11.
Dual USB Host Connector (J31, J32)
The USB module of the i.MX53 processor provides a high speed USB PHY that is connected to a USB HUB
(USB2514). Two of the USB ports are dedicated to USB HOST. Both jacks receive 5V power from DCDC_5V
through a power monitor that can be controlled by software.
3.12.
Micro-B USB Device Connector (J34)
The micro USB connector is connected to the USB OTG PHY on the i.MX53 processer and supports full OTG
function.
3.13.
Audio Input/Output (P1/J130/CON1)
Analog audio input and output are provided by Freescale’s Low Power Stereo Codec, SGTL5000. The audio
codec is connected to the i.MX53 processor through four-wire I2S communications, utilizing the AUDMUX5
port of the processor. The audio codec’s Headphone Amp provides up to 58 mW output to 16Ω headphones at
a typical SNR of 98 dB and THD+N of -86 dB. Typical power consumption is 11.6 mW. In addition, the audio
codec can perform several enhancements to the output, including virtual surround, added bass, and three
different types of equalization. The Microphone Input module of the Stereo Codec is also used, while the
microphone is applied on the MCIMX53SMD board. A Headphone Jack (J130) and Speaker Connector (CON1)
are on the MCIMX53SMD board. A 3.5 mm Headphone with plug-in detect is supported. Two speakers with 8Ω
impedance rating and 1W power rating are attached through a power amplifier (TS4984IQT).
3.14.
15V Power Connector (J35)
A 2.0 mm x 6.5 mm barrel connector is used which should fit standard DC Plugs with an inner dimension of 2.1
mm and an outer dimension of 5.5 mm. If a secondary power supply is used, it should not supply more than
15V power at 3A output. If the PMIC senses too high voltage at the connector input, it will turn off to protect
the MCIMX53SMD board. If a Wall Power Supply is connected to the MCIMX53SMD board, the red 15V power
LED indicator will light.
3.15.
Mini-PCIe Connector (J15, J18)
Two mini-PCIe connectors are on the MCIMX53SMD board. One for 3G modem, the other is for WiFi/BT. The
MCIMX53SMD board provides just a standard mini-PCIe slot for 3G Modem. So, the developers can use a 3G
Modem of their choice. For the WiFI/BT module, the MCIMX53SMD board uses the module based on the
Atheros. The module pin map is not compatible with the standard mini-PCIe. Therefore, care must be taken to
plug the module to the right mini-PCIe slot.
