CVBS analog video output is available with Tamron MP1110M-VC only. In this case the camera monitoring mode (register 72) must be set to NTSC or PAL video. Refer to Tamron MP1110M-VC technical manual for further details. In NTSC or PAL mode, there will be no SDI output signal available from TL8656. CVBS output connector J5 is available on Rev.B boards from September 26, 2018.
