4.10 Sinchronous Serial Controller
The application processor provides a Sinchronous serial controller that can support several serial
synchronous communication protocols such as: I2S, Short Frame Sync, Long Frame Sync.
With this peripheral the processor can be interfaced with Audio Codecs, Fast DAC, Fast ADC.
4.11 Ethernet controller
The Application processor provides an Ethernet controller compatible with the 10Mb/s -100Mb/s IEEE
802.3 standard that can be used to interface the Telit GE863-PRO
3
to a LAN. It fully supports Media
Independent Interface (MII) or Reduced Media Independent Interface (RMII) standards to PHY
transceivers with MDIO controlling interface.
4.12 ADC with ADC trigger
The application processor provides an Analog Digital Converters with an ADC trigger input and a
4-to-1 analog multiplexer, making possible the conversion of up to 4 analog lines.
The characteristic of the ADC are:
Min Max Units
Voltage range
3.0 3.1 Volt
AD conversion
8 10 bits
ADC clock frequency
0 5 MHz
Max sampling rate 312 kS per second
4.13 DAC Converter
The Application processor is able to generate a PWM signal based on a specific percentage of duty
cycle decided by the user. An external filter is necessary to convert the PWM signal into a constant
voltage.
