Description
Dual or triple standard, and Cyclone IV GX devices only. You must turn
on this option if you select an EP4CGX110 or EP4CGX150 device.
Enables an additional input port for transmitter serial reference clock.
Available for Arria II, Stratix IV, and HardCopy IV devices only.

Description
Turns on or off CRC monitoring (HD-SDI and 3G-SDI only).
Provides synchronization outputs.
Receiver protocol only. Allows you to set the number of consecutive
missing EAVs to be tolerated in the incoming video. Specify a higher
value if you want the receiver core to tolerate more errors.
If you want the receiver core not to tolerate any errors, set this option to
0 .
HD-SDI transmitter only. When turned on, runs the transceiver at twice
the rate and has improved jitter performance. Requires 148.5-MHz
tx_serial_refclk reference clock.
MegaCore Verification
The MegaCore verification involves testing to the following standards:
For the SD-SDI to SMPTE259M-1997 10-Bit 4:2:2 Component Serial Digital Interface
For the HD-SDI to SMPTE292M-1998 Bit-Serial Digital Interface for High Definition
