Design Example
February 2013 Altera Corporation Serial Digital Interface (SDI) MegaCore Function
User Guide
Table 4–31 lists the function of each user-defined dual in-line package (DIP) switch
settings.
D18
Indicates that the receiver of the SDI duplex MegaCore function is TRS
locked.
D17
Indicates that the receiver of the SDI duplex MegaCore function is frame
locked.
D16 Indicates the recovered clock heartbeat of the receiver.
D13 Indicates the ancillary checksum failure.
D12 Indicates the ancillary parity failure.
D11 Indicates the channel status CRC failure.
D10 Indicates the audio packet failure.
D9-D8
Indicate the SDI receive video standards.
00 = SD-SDI, 01 = HD-SDI, 11 = 3G-SDI Level A, 10 = 3G-SDI Level B
D7-D6
Indicate the SDI transmit video standards.
00 = SD-SDI, 01 = HD-SDI, 11 = 3G-SDI Level A, 10 = 3G-SDI Level B
Table 4–31. Function of Each DIP Switch
DIP Switch Description
8 Resets the system.
7 Resets the Audio Extract MegaCore function status registers.
6-3 Unused.
2-1
Configure the internally-generated video standards for both SDI transmitters.
00 = SD-SDI, 01 = HD-SDI, 11 = 3G-SDI Level A, 10 = 3G-SDI Level B
When 00, enables the embedding of audio group 1,
When 01, enables the embedding of audio group 1 and 2,
When 11, enables the embedding of audio group 1, 2, and 3,
When 10, enables the embedding of audio group 1, 2, 3, and 4
