The main building blocks of the AMN12310 are as follows:
• AMN2210 WHDI Baseband Receiver, as briefly described on page 12
• STM32F MAC µController, as briefly described on page 12
• AMN3210 WHDI
TM
5GHz Transceiver, as briefly described on page 13
• Power Amplifier (PA), as briefly described on page 13
• Board Connector (WHDI
TM
Connector), as described on page 13
• Clock enable switch for input 40M clock to AMN2110 , as described on page 13

2.1 AMN2210 WHDI Baseband Receiver
The AMN2210 WHDI
TM
baseband receiver chip is the heart of the AMN12310 WHDI Receiver module. The
AMN2210 interfaces the A/V source through the WHDI connector, and is controlled on board by the MAC uC.

Figure 2: WHDI Baseband Receiver Chipset
The AMN2210 is based on MIMO technology receiving up to five input channels. Five analog-to-digital converters
and one digital-to-analog converter are embedded within the chip.
The AMN2210 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 the option to work with an internal 4-to-16 MHz crystal oscillator.
