VP5311C/VP5511C
NTSC/PAL Digital Video Encoder
Supersedes May 1997 edition DS4575 - 1.0 DS4773 - 2.3 March 1998
The VP5311C/VP5511C converts digital Y, Cr, Cb, data into analog NTSC/PAL composite video and S-video s i g n a l s . 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 Cb, Y, Cr, Y (i.e. 4:2:2). The video blanking and sync information from REC 656 is included in the data stream when the VP5311C/ VP5511C is working in slave mode. The output pixel rate is 27MHz and the input pixel rate is half this frequency, i.e. 13.5MHz. All necessary synchronisation signals are generated internally when the device is operating in master mode. In slave mode the device will lock to the TRS codes or the HS and VS inputs. The rise and fall times of sync, burst envelope and v i d e o blanking are internally controlled to be within composite video specifications. Three digital to analog converters (DACs) are used to convert the digital luminance, chrominance and composite data into true analog signals. An internally generated reference voltage provides the biasing for the DACs.
