ES3207  
Video CD/DVD Companion Chip  
Product Brief  
DESCRIPTION  
FEATURES  
The ES3207 Video CD/DVD Companion Chip provides an  
optimal system design for a Video CD player or a DVD  
player.  
Multi-standard TV encoder:  
– CCIR601 non-square operation  
– NTSC/PAL formats  
The ES3207, which is an enhanced version of the pin-  
compatible ES3205, integrates most of the required  
analog discrete components into a simple, cost-effective  
solution and interfaces directly to the ES3210 (Video CD)  
or ES3308 (DVD). No glue logic or external microcontroller  
is required.  
– Master video mode  
– 8-bit interface for YCrCb (4:2:2) input format  
– Simultaneous composite and S-video output  
– Interlaced operation  
Audio DACs:  
The ES3207 features include a high-quality NTSC/PAL  
Digital Video Encoder (DVE), echo, echo reverb,  
3DSound, surround sound, video and audio DACs, and a  
PLL clock synthesizer. There are three 9-bit video DACs  
(one for composite video output and two for S-video  
outputs) and two 16-bit sigma-delta audio DACs for  
interfacing with current sound systems.  
Two 16-bit sigma-delta DACs  
Accepts I2S format data  
Programmable functions  
3DSound and surround sound  
Remote control interface for power on/off  
Digitally controlled echo with up to 168 ms delay  
Vocal reverb for theater acoustical effects  
Dual microphone input  
The DVE generates composite and S-video analog  
signals. Color Space Conversions (CSC) are provided to  
match the input data to the required output format, then  
the data is filtered to meet the selected video standards. In  
addition, the ES3207 is equipped with a remote control  
interface for power on/off, microphone ports, auxiliary  
ports, and an interface for accessing internal registers.  
Clock synthesizer (PLL):  
Based on 27 MHz crystal input  
Generates required clocks for video encoder, audio  
DAC, echo and surround sound, and video  
processor
