Notes
1. This maximum value has an absolute maximum of 6.5 V independent of the supply voltage.
2. The human body model ESD simulation is equivalent to discharging a 100 pF capacitor via a 1.5 k resistor, which produces a single discharge transient. Reference "Philips Semiconductors Test Method UZW-BO/FQ-A302 (similar to MIL-STD 883C method 3015.7)".
3. The machine model ESD simulation is equivalent to discharging a 200 pF capacitor via a resistor and series inductor with effective dynamic values of 25 and 2.5 H, which produces a damped oscillating discharge. Reference "Philips Semiconductors Test Method UZW-BO/FQ-B302 (similar to EIAJ IC-121 Test Method 20 condition C)".
DescriptionSAA7335 is a high-end combined Compact Disc (CD) and Digital Versatile Disc (DVD) compatible decoding device. The device operates with an external 32 kbytes S-RAM memory for de-interleaving operations. The SAA7335 provides quad-pass error correction for CD-ROM applications (C1-C2-C1-C2) and operates in lock-to-disk, CAV, pseudo CLV and CLV modes.
In DVD modes double-pass C1-C2 error correction of SAA7335 is used which is capable of correcting up to 5 C1 frame errors and 16 C2 frame errors.
The SAA7335 contains all the functions required to decode an EFM or EFM+ HF signal directly from the laser pre-amplifier, including analog front-end, PLL data recovery, demodulation and error correction. The spindle motor interface provides both motor control signals from the demodulator and, in addition, SAA7335 contains a tachometer loop that accepts tachometer pulses from the motor unit.
The SAA7335 has two independent microcontroller interfaces. The first is a serial I2C-bus and the second is a standard 8-bit multiplexed parallel interface. Both of these interfaces provide access to a total of 32 ´ 8-bit registers
for control and status.
This data sheet of SAA7335 contains an descriptive overview of the device together with electrical and timing characteristics. For a detailed description of the device refer to the user guide "SAU/UM96018".
Supply of this CD/DVD IC SAA7335 does not convey an implied license under any patent right to use this IC in any CD or DVD application.
