Passive Cooling
The passive cooling policy employs the technique of enhancing conduction and natural convection. This passive thermal management procedure
provides cost effective cooling solutions up to certain power levels without introducing reliability concerns. Some of these techniques typically
used are thermal gap fillers, heatspreaders and heat shields.

Audio Mux

Audio Mux (AUDMUX) is one of the modules found in the audio subsystem of the NXP
routing of the on-chip serial interfaces to and from off-chip devices. The AUDMUX includes internal port that connect to the processor serial
interfaces and external ports that connect to off-chip audio devices. Connection is established by configuring the appropriate host and
peripheral ports. Though controlled by ARM, the AUDMUX can route data even when the ARM is in a low-power mode.

LVDS Bridge

The LVDS Bridge (LDB) supports the flow of synchronous RGB data from the Image Processing Unit to external devices through LVDS interface.
This support includes synchronization and control capabilities, connectivitity to relevant devices as well as proper data arrangement as required
by the external display receiver and by LVDS display standards.

USB Port Connections

The conga-QMX6 offers a total of 5 USB ports (one USB OTG port and four Host-only ports). The four Host-only ports found on the conga-QMX6
are implemented by routing one Host-only port (USB H1) from the NXP
The USB_OTG port (OTG client) of the conga-QMX6 is routed directly to the USB_OTG port of the i.MX6 processor. This port can drop the
hosting role and act as a normal USB device when conga-QMX6 is attached to another host. It is also used as a downstream and upstream port
while the Host-only cores are used as downstream ports.
