2.1 AMN2110 WHDI Baseband Transmitter
The AMN2110 WHDI
TM
baseband transmitter chip is the heart of the AMN11310 WHDI transmitter module. The
AMN2110 interfaces the A/V source through the WHDI connector, and is controlled on board by the MAC uC.

Figure 2: WHDI Baseband Transmitter Chipset
The AMN2110 is based on MIMO technology transmitting through up to four output channels. Four
digital-to-analog converters and one analog-to-digital converter are embedded within the chip.
The AMN2110 internal PLL accepts an input clock frequency of 40MHz. The input frequency is multiplied and
then used as an internal system clock.
2.2 STM32F MAC µController
The STM32F Microcontroller is based on an ARM 32-bit Cortex™-M3 CPU, with 128 Kbytes of embedded Flash
memory. It is used as an external microcontroller for implementing the MAC layer of the WHDI link.
The STM32F Internal PLL accepts an input clock frequency of 10MHz and generates an internal 60MHz system
clock. The STM32F also has an option to work with an internal 4-to-16 MHz oscillator.
