2.10.3.2 McASP

The AM275x features five Multichanel Audio Serial Ports (McASP), McASP[0:4]. Each McASP features independent clock zones for transmit and receive.

McASP1 is used for AM275x EVM on-board ADC/DAC Input and Outputs.

The ADC/DAC Input and Outputs featured on the AM275x EVM consist of:

  • Four output 3.5mm TRS Audio Jack connectors for Eight Stereo Channel DAC Line AC-coupled outputs. Each individual TRS Audio Jack Connector is connected to a two-channel Stereo Audio DAC(TAD5212) device (four DACs in total).
  • Four input 3.5mm TRS Audio Jack connectors for Eight Stereo Channel Microphone/Line AC-coupled inputs. Each Pair of the TRS Audio Jack Connectors are connected to a four-channel Audio ADC(PCM6240) device (two ADCs in total).

McASP0 is used as the primary McASP interface for Audio Expansion Connector 1 (AEC1). McASP0 has Eight Audio Transmit/Receive channels(McASP0_AXR[0:7]) .

McASP4 is used as the secondary McASP interface for Audio Expansion Connector 1 (AEC1). McASP4 has Four Transmit/Receive channels (McASP4_AXR0, McASP4_AXR[3:5]). McASP4 can be routed to the McASP4/MLB Header through a 1:2 MUX (SN74CBTLV). Routing McASP4 to MLB Header requires population jumper J29 to define I/O Voltage level on MLB Header.

McASP2 is used as the primary McASP interface for Audio Expansion Connector 2 (AEC2). McASP2 has Six Audio Transmit/Receive channels (McASP2_AXR[0:5]).

McASP3 is used as the primary McASP interface for Audio Expansion Connector 2 (AEC2). McASP3 has Four Audio Transmit/Receive channels (McASP3_AXR[0:3]).
