The VP5311/VP5511 converts digital Y, Cr, Cb, data into analog NTSC/PAL composite video and S-video signals. The outputs are capable of driving doubly terminated 75 ohm loads with standard video levels.

The device accepts data inputs complying with CCIR Recommendation 601 and 656. The data is time multiplexed on an 8 bit bus at 27MHz and is formatted as Y, Cr, Y, Cb (i.e. 4:2:2). The video blanking and sync information from REC 656 is included in the data stream when the VP5311/ VP5511 is working in slave mode.
