2.3 AMN3210 WHDI
TM
5GHz Transceiver
The VDU uses AMN3210 WHDI receiver chip. The AMN3210 is a fully integrated Zero-IF MIMO receiver
specifically designed for WHDI applications using OFDM modulation for single-band 4.9GHz to 5.9GHz. The
device includes:
• Five Complete Downlink Zero-IF Receivers
• One Uplink Direct Conversion Transmitter
• Integrated Synthesizer/VCO
• Internal DC Servo Loops
• RSSI, RF and Baseband Control Interface
• Power Management Unit
•
3-Wire SPI Interface
To complete RF front-end solution, the AMN3210 uses external PA, RF Band Pass Filters (BPF), RF BALUNs
and a few passive components.
2.4 Power Amplifier (PA)
In order to extend the operating range for the AMN12310 upstream, the RF transmitter uses a power amplifier.
The power amplifier has an output power detector for TPC purposes.
AMN12310 uses Sharp IRM053U7 PA.
2.5 Board Connector (WHDI
TM
Connector)
For information regarding the connector specification and pin-outs see section 4.1 , Signals , page 26.
2.6 Clocks
2.6.1 40MHz Crystal Oscillator
An on-board 40MHz crystal oscillator is connected to the AMN3210 chip.
2.6.2 40Mhz Digital Clock
AMN3210 drives the 40MHz clock to the baseband AMN2210 through a buffer (with output enable).
This clock is named DIG_CLK. The control to the output buffer is named Clk40M_OE.
2.6.3 10Mhz Micro Controller Clock
The DIG_CLK (40MHz) clock is divided by four by the AMN2210 and generates 10MHz that drives the STM32F
UC.
