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 Freescale

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.

8.4

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.

8.5

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 Freescale

USB Hub.

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.
