Hello,

I am looking to interface a TVP5158 video decoder and a TMS320C6746 DSP. We wish to use the 4-channel D1, line interleaved output mode.

I know that the TVP5158 can output 16-bit YCbCr video data with embedded syncs @ 54MHz. (I am assuming this is within the BT-1120 spec)

However, the TMS320C6746 VPIF user's guide (sprugj9a.pdf), section 2.15.2 states: "The BT.1120 mode
requires an input clock source of 74.25 MHZ."

Will the TMS320C6746 VPIF, set in BT-1120 mode, work at an input clock rate of 54MHz?

Regards,

Nick
