SAA7818HL

DVD and CD playback IC

x Supports real-time error detection and correction in hardware for CD-ROM mode

x CD-ROM error corrector switchable between single or dual pass; both with Error

Detection/Correction (EDC)

x Internal registers are memory mapped

x Embedded DVD video authentication module.

s Buffer memory controller:

x Support for up to 64 Mbit external SDRAM memory

x Block based sector addressing.

s Channel decoder:

x Selectable differential and single-ended HF inputs; compatible with the TZA1036

and TZA1038; single-ended input has bypassable AGC

x Internal 8-bit ADC

x Digital PLL and slicer for HF clock regeneration

x Supports EFM and EFM+ demodulation

x Full CD error correction strategy; t = 2 and e = 4

x On-chip CD error corrector memory with Â±8 frame jitter margin

x Built-in hardware for double pass DVD error corrector; can correct 5 errors in C1

frame; 16 errors in C2 frame

x Error corrector monitor signal available

x I2S-bus output available via programmable vampire pins

x Programmable frame sync loss indication

x Increased tap settings for PLL equalizer compared with SAA7816

x Enhanced playability of black dots and scratches with improved defect detector; it

enables the HF PLL frequency, slicer, high-pass ï¬lter, AGC and offset loops to be

held when a defect is detected

x Improved tolerance to continuity errors in DVD play mode

x Limit equalizer

x Two extra motor gain settings compared to SAA7816

x Support for copyright protection strategy for games applications

x Hardware AGC loop, in combination with front-end IC (TZA1038)

x Hardware automatic offset compensation loop, in combination with front-end IC

(TZA1038)

x Average jitter can be read back

x Internal digital high-pass ï¬lter on HF input, with programmable cut-off frequencies

x Run Length 3 (RL3) pushback feature

x PLL monitor signal available

x Interpolate and hold on audio output.

s Spindle motor control:

x Advanced motor control loop allows CAV, CLV and pseudo-CLV playback

x Support for 3-pin and 1-pin tacho control

x Motor control via incoming bitstream or tacho.

s Speed operation:

x Supports 18 Ã CD-ROM playback

x Supports 6 Ã DVD-ROM playback.
