Overview
The main building blocks of the HM500 are as follows:
• AMN2110 WHDI Baseband Transmitter, as briefly described on page 4
• STM32F103RBT6 Mini-MAC µController, as briefly described on page 4
• MAX2828 5GHz (802.11a) Transceiver, as briefly described on page 5
• Power Amplifier (PA), as briefly described on page 5
• Board Connector (WHDI Connector), as described on page 5
• EEPROM, as described on page 5
• 40MHz Clock Gen, as described on page 5
2.1 AMN2110 WHDI Baseband Transmitter
The AMN2110 WHDI
TM
baseband transmitter chip is the heart of the HM500 WHDI transmitter module. The
AMN2110 interfaces the A/V source through the WHDI connector, and is controlled on board by the MiniMAC uC.

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 STM32F103RBT6 Mini-MAC µController
The STM32F103RBT6 microcontroller is based on a 32-bit ARM7TDMI-S CPU, with embedded 128kB high-
speed memory. It is used as an external microcontroller for implementing the MAC layer of the WHDI link.
The STM32F103RBT6 internal PLL accepts an input clock frequency of 40MHz.
