CS98200

Next Generation DVD Processor

5.10

Video Encoder with Progressive Video

DACs

The CS98200 incorporates an enhanced video

encoder with six 10-bit video DACs that drive

double terminated 75

Ω directly without exter-

nal buffering. These termination resistors

should be located as close as possible to the

CS98200. All analog video outputs should be

connected through filters to video connectors

(TV/Monitor). The video filters should be locat-

ed as close as possible to the video connectors.

Two schottky diodes should be connected to

each output in order to protect the CS98200

from surges caused by being connected and dis-

connected to the external devices. Figure 21

shows the video DAC connections.

Six 10-bit DACs provide two channels for an S-

Video output port, one composite video output,

and three RGB or Y, Pb, Pr outputs. Video out-

put can be formatted to be compatible with

NTSC (M,J), PAL (B, D, G, H, I, M, 60), and 480P.

The video encoder is compliant with both Mac-

rovision 7.1 for the interlaced video (NTSC,

PAL) and 1.03 for the progressive scan (480p).

The video encoder also supports WSS (Wide-

Screen Signaling), CGMS (Copy Generation

Management System), and Closed Caption.
