SAM0076-051701 1 ES3207 Video CD/DVD Companion Chip Product Brief DESCRIPTION The ES3207 Video CD/DVD Companion Chip provides an optimal system design for a Video CD player or a DVD player. 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. 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. 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. Figure 1 shows a block diagram of a typical stand-alone system using the ES3210 Video CD Processor Chip or the ES3308 MPEG2 Audio/Video Decoder Chip and an ES3207 Video CD Companion Chip. FEATURES • Multi-standard TV encoder: – CCIR601 non-square operation – NTSC/PAL formats – Master video mode – 8-bit interface for YCrCb (4:2:2) input format – Simultaneous composite and S-video output – Interlaced operation • Audio DACs: – 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 • Clock synthesizer (PLL): – Based on 27 MHz crystal input – Generates required clocks for video encoder, audio DAC, echo and surround sound, and video processor • Device Serial Communication (DSC) port for command issued/register access • Power management • 100-Pin PQFP • Single 5 V power supply Figure 1 ES3207 Video CD Companion Chip System Block Diagram ES3207 DRAM Remote VFD VFD Driver Panel Receiver ES3210 CD-ROM Audio DAC 3D/Echo/Surround PLL NTSC/PAL Video DSC ROM Television Speakers (Video CD) or ES3308 (DVD) or DVD-ROM Drive Preamp Volume Control Preamp Volume Control Mic 1 Mic 2 |
