INTEGRATED CIRCUITS DATA SHEET SAA2510 Video CD (VCD) decoder Preliminary specification File under Integrated Circuits, IC02 1996 May 21 Philips Semiconductors Preliminary specification Video CD (VCD) decoder FEATURES (With standard microcode loaded) • Decoding and display of MPEG1 video streams (constrained parameters) • Decoding of MPEG audio streams (layer II) • Decoding, storage (compressed) and display of high-resolution still pictures of 704 × 576 pixels • Requires only 4 Mbits of external 70 ns DRAM • Audio transparency mode for CD-DA discs • On-screen display capability • Play options: – Play – Stop – Pause/continue – Slow-motion forward – Scan forward – Scan backward. • Supports auto-pause feature • Disc interface: Philips I2S, EIAJ, MEC formats and IEC 958 (EBU) interface • Separate error flag input (EFIN) and data valid input (NDAV) • Performs basic block decoder functions: – serial-to-parallel conversion – sync detection – descrambling – EDC calculation – error-correction for mode 2 form 1 sectors – header and sub-header interpretation. • I2C-bus interface • Video output YUV 4 : 2 : 2 format. DMSD bus compatible • Also supports CCIR656 video interface, including line and field timing codes • Audio output: 44.1 kHz. 16, 18 or 20 bits per audio sample in Philips I2S, Sony or MEC formats ORDERING INFORMATION PACKAGE TYPE NUMBER NAME SAA2510 QFP100 DESCRIPTION plastic quad flat package; 100 leads (lead length 1.95 mm); body 14 × 20 × 2.7 mm; high stand-off height 2 APPLICATION • Dedicated video CD players. GENERAL DESCRIPTION SAA2510 • EBU audio output, fully transparent from input to output in CD-DA mode and generated in MPEG mode • Downloadable microcode for internal controllers • Internal video timing generator • Requires 40 MHz crystal for system clock generation • Requires 27 MHz crystal or external 27 MHz source for video timing generation • Requires 16.9344 MHz (384 × 44.1 kHz) clock locked to CD drive • Internal generation of 90 kHz MPEG clock • Capability of sharing external DRAM by 3-stating all DRAM pins. MPEG1 audio and video CD (VCD) decoder, intended for use in low-cost dedicated video CD players. When used with a 4 Mbit DRAM and a digital video encoder, the decoder adds the required functionality to a CD decoder to implement a low-cost video CD player capable of playing discs coded to version 2.0 of the video CD specification. The SAA2510 is an I2C-bus controlled chip and features serial data input in four common bus formats. It provides digital video output in CCIR601 and 656 formats. A bit-mapped on-screen display is provided and output video timing can be 525 lines/30 frames per second or 625 lines/25 frames per second. The chip is microcode programmable for feature enhancement.
