SAA6752HS/V104,557

Encoders, Decoders, Converters Overview

The SAA6752HS/V104,557 is a second-generation real-time MPEG-2 video and MPEG-audio encoder with an integrated multiplexer. It accepts digital YUV input compliant with ITU-R BT.656 and BT.601 standards, supporting resolutions up to D1. The device performs MPEG-2 Main Profile at Main Level encoding for interlaced line systems and supports MPEG-1 Layer 2 audio compression. Unlike the V103 variant, this version excludes Dolby Digital Consumer Encoding (AC-3) functionality. It interfaces with external SDRAM (16 Mbit or 64 Mbit @ 16-bit) and outputs multiplexed streams via a parallel interface compatible with IEEE 1394 chipsets.

Encoders, Decoders, Converters Feature Summary

• Integrated MPEG-2 video compression with adaptive quantization and motion estimation
• MPEG-1 Layer 2 audio encoding capability
• Multiplexer generating Transport Streams, Program Streams, and Packetized Elementary Streams
• I2C-bus control domain for configuration and status monitoring

Encoders, Decoders, Converters Applications

• DVD-based optical disc recorders (DVD+RW, DVD-RW, DVD-RAM)
• Hard disk drive based time-shift recording systems
• Digital Video Home System (DVHS) recording devices
• Video editing, transmission, surveillance, and conferencing equipment

Encoders, Decoders, Converters Procurement Notes

Verify that the specific application does not require AC-3 audio encoding, as the V104 variant lacks this feature compared to the V103. Confirm system memory requirements align with the supported 16 Mbit or 64 Mbit SDRAM configurations. Ensure the host processor can manage I2C-bus communication for initialization and dynamic parameter adjustments during operation.

Encoders, Decoders, Converters Selection Notes

Select the SAA6752HS/V104 when AC-3 encoding is unnecessary to reduce component complexity. This part replaces the legacy SAA6752HS/V102 with enhanced functionality. Designers must account for the SQFP208 package dimensions and ensure proper thermal management given the total power dissipation characteristics of the device under load.

Encoders, Decoders, Converters Part Context

This component belongs to Philips Semiconductors' second generation of real-time MPEG-2 encoders. It consolidates video preprocessing, compression, audio encoding, and stream multiplexing into a single chip, reducing the bill of materials from three chips to one. The V104 suffix specifically denotes the version without AC-3 support, targeting applications where MPEG-1 Layer 2 audio is sufficient.

Encoders, Decoders, Converters Replacement Considerations

The SAA6752HS/V104 serves as a replacement for the SAA6752HS/V102 with enhanced functionality. If AC-3 encoding is required, the SAA6752HS/V103 should be selected instead.
