5.3. SDI Audio Clocked Input Signals

The following tables list the signals for the SDI Audio Clocked Input IP cores.

Table 20.  SDI Audio Clocked Input Input and Output Signals
Signal Width Direction Description
aes_clk [0:0] Input Audio input clock.
aes_de [0:0] Input Audio data enable.
aes_ws [0:0] Input Audio word select.
aes_data [0:0] Input Audio data input in internal AES format.
Table 21.  SDI Audio Clocked Input Avalon Streaming Interface Audio SignalsThis table lists the Avalon-ST audio signals when you instantiate the SDI Audio Clocked Input IP core in Platform Designer (Standard).
Signal Width Direction Description
aud_clk [0:0] Input Clocked audio clock. All the audio input signals are synchronous to this clock.
aud_ready [0:0] Input Avalon streaming interface ready signal. Assert this signal when the device is able to receive data.
aud_valid [0:0] Output Avalon streaming interface valid signal. The core asserts this signal when it produces data.
aud_sop [0:0] Output Avalon streaming interface start of packet signal. The core asserts this signal when it is starting a new frame.
aud_eop [0:0] Output Avalon streaming interface end of packet signal. The core asserts this signal when it is ending a frame.
aud_data [23:0] Output Avalon streaming interface data bus. The core asserts this signal to transfer data.
Table 22.  SDI Audio Clocked Input Direct Control Interface SignalsThe direct control interface is internal to the audio extract component.
Signal Width Direction Description
channel0 [7:0] Input Indicates the channel number of audio channel 1.
channel1 [7:0] Input Indicates the channel number of audio channel 2.
fifo_status [7:0] Input Drive bit 7 high to reset the clocked audio input FIFO buffer.
fifo_reset [0:0] Output Assert this signal when the clocked audio input FIFO buffer overflows.
