DPL 35xxA
Dolby Pro Logic Processor Family 1. Introduction The DPL 35xxA processor family is designed to decode Dolby encoded surround sound. The ICs integrate the complete Dolby Surround Pro Logic decoding on chip without any necessary external circuitry. This data sheet describes the features and specifications of all members of the IC family. The DPL 3518A is designed as a coprocessor to one of the TV sound processing ICs of the MSP 34xx family. It only has digital interfaces. No analog input and output interfaces are supported. The DPL 3519A is also designed as a coprocessor to the MSP family but has analog output channels in addition to the features of the DPL 3518A. Together with the MSP, a TV set with up to six outputs (L, R, C, SUB, SL, SR) can be developed together with headphones and several line outputs. The DPL 3520A is designed as a stand-alone Dolby Surround Pro Logic decoder. An on-chip A/D converter digitizes analog inputs. The DPL 3520A can also be used as a coprocessor to the MSP 34xx single-chip Multistandard Sound Processor family. This gives another A/D input pair to the system. The ICs of the DPL family are pin-compatible to the MSP ICs. This speeds up PCB development for customers using MSPs. The software interface is largely the same as for the MSP 3400C. Volume, tone controls, matrixes and switches use the same registers and values. Thus, the standard MSP 3400C controlling software can be used to control the DPL 3520A. Little overhead is needed to control the Dolby Pro Logic part of the IC.

DPL 3518A Integrated Functions: Full Dolby Surround Pro Logic Adaptive Matrix Pseudo-surround mode for signals not encoded in Dolby Surround PANORAMA sound mode (3-D Surround sound via 2 loudspeakers) Noise sequencer Automatic input balance control 7 kHz low-pass filter 100 Hz low-pass filter for subwoofer Modified Dolby B-type NR decoder 30 ms surround delay according to table created by Dolby Laboratories (1 ms steps) 2 I2S input channels (e.g. MSP and DRPA) 2 I2S output channels, freely programmable with sound channels L/R (resp. L)C/R)C), C/S, Sub or I2S input Mode control: normal/phantom/wide/three channel/center off/panorama sound/stereo bypass Surround matrix mode control: adaptive/passive/effect Additional surround basewidth effect Reverberation of surround signals 2 digital input/output pins 1 digital input pin
DPL 3519A Integrated Functions (in Addition to all DPL 3518A Functions): Master volume control in dB units Level Trim for L, C, R, S in dB units, $12 dB Identical treble/bass/loudness function for L, C, R, S 5-band equalizer for C channel Separate volume control for two surround outputs Additional line output for HIFI receiver connection (SCART output). Volume for this output is in dB units. 3 pairs of D/A converters Scart switches
DPL 3520A Integrated Functions (in Addition to all DPL 3518A and DPL 3519A Functions) 1 pair of A/D converters Note: the 5-band equalizer for C channel can only be used in coprocessor mode. No parallel AD input possible.
DPL 3520/19/18A Applications: Dolby Pro Logic Surround System in television sets in satellite receivers in video recorders
