3 / 68 page 2000 Jun 26 3 Philips Semiconductors Product specification Digital servo processor and Compact Disc decoder with integrated DAC (CD10 II) SAA7324 1 FEATURES • Integrated bitstream DAC with differential outputs, operating at 96fs with 3rd-order noise shaper; typical performance of −90 dB signal-to-noise ratio • Separate serial input and output interfaces allow data ‘loopback’ mode for use of onboard DAC with external Electronic Shock Absorption (ESA) systems • Up to 4 times speed mode • Low voltage operation at up to 2 times speed • Lock-to-disc mode • Full error correction strategy, t = 2 and e = 4 • Full CD graphics interface • All standard decoder functions implemented digitally on chip • FIFO overflow concealment for rotational shock resistance • Digital audio interface (EBU), audio and data • Two and four times oversampling integrated digital filter, including fs mode • Audio data peak level detection • Kill interface for external DAC deactivation during digital silence • All SAA737x (CD7) digital servo and high-level functions • Low focus noise • Same playability performance as SAA737x (CD7) • Automatic closed-loop gain control available for focus and radial loops • Pulsed sledge support • Electronic damping of fast radial actuator during long jump • Microcontroller loading LOW • High-level servo control option • High-level mechanism monitor • Communication may be via TDA1301/SAA7345 compatible bus or I2C-bus • On-chip clock multiplier allows the use of 8.4672, 16.9344 or 33.8688 MHz crystals or ceramic resonators. 2 GENERAL DESCRIPTION The SAA7324 (CD10 II) is a single chip combining the functions of a CD decoder, digital servo and bitstream DAC. The decoder/servo part is based on the SAA737x (CD7) and is software compatible with this design. Extra functions are controlled by use of ‘shadow’ registers (see Section 7.15.3). Supply of this Compact Disc IC does not convey an implied license under any patent right to use this IC in any Compact Disc application. 3 ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION SAA7324H QFP64 plastic quad flat package; 64 leads (lead length 1.6 mm); body 14 × 14 × 2.7 mm SOT393-1 |
