reconfig
1 Output Request to start dynamic reconfiguration. Applicable for dual
standard and triple standard modes only.
rx_sdi_reconfig_
done
1 Input Indicates that dynamic reconfiguration has completed.
Applicable for dual standard and triple standard modes only.
rx_clkin_
smpte372
1 Input Clock input for level A to level B and level B to level A
operations.
• Level A to level B = 148.5 MHz or 148.35 MHz
• Level B to level A = 74.25 MHz or 74.175 MHz
