SAA6752HS/V103,557

Encoders, Decoders, Converters Overview

The SAA6752HS/V103,557 is a second-generation real-time MPEG-2 video and MPEG-audio/AC-3 audio encoder with multiplexer. It accepts digital YUV input via ITU-R BT.656 or BT.601 formats at 8 bits and 27 MHz. The device performs real-time MPEG-2 encoding compliant with Main Profile at Main Level (MP@ML) for 625 and 525 interlined line systems, supporting resolutions of D1, 2/3D1, 1/2D1, and SIF. Audio compression includes Dolby Digital Consumer Encoding (DDCE/AC-3) at 256 kbit/s or 384 kbit/s, alongside MPEG-1 Layer 2 encoding. Stream multiplexing generates MPEG-2 Transport Streams (TS), Program Streams (PS), Packetized Elementary Streams (PES), and Elementary Streams (ES). The chip utilizes a single external SDRAM (16 Mbit or 64 Mbit @ 16-bit) and operates on 3.3 V and 2.5 V supplies within a 0 to 70 °C ambient temperature range.

Encoders, Decoders, Converters Feature Summary

• Integrated MPEG-2 video compression with noise filtering and motion estimation capabilities.
• Supports AC-3 and MPEG-1 Layer 2 audio encoding with flexible input formats.
• Multiplexes encoded streams into DVD, D-VHS, and DVB compliant formats.
• Controlled entirely via I2C-bus interface with internal MIPS processor.

Encoders, Decoders, Converters Applications

• DVD-based optical disc recorders (DVD+RW, DVD-RW, DVD-RAM)
• HDD-based time-shift recording systems
• Digital VCR (DVHS) recording devices
• Video editing, transmission, surveillance, and conferencing

Encoders, Decoders, Converters Procurement Notes

Verify the ordering suffix /V103,557 against the manufacturer's current product specification to confirm package type SQFP208 and lead length specifications. Ensure compatibility with required SDRAM memory configurations and I2C bus addressing before integration.

Encoders, Decoders, Converters Selection Notes

Select this component when AC-3 audio encoding is required alongside MPEG-2 video compression. The V103 variant replaces the V101 with enhanced functionality. Consider the V104 version if AC-3 encoding is not needed. Verify system clock requirements for 27 MHz operation and available GPIO pins for specific application interfaces.

Encoders, Decoders, Converters Part Context

This part belongs to the Philips Semiconductors (now NXP) SAA6752HS family of integrated circuits. It represents a highly integrated single-chip solution designed to reduce system cost by consolidating video, audio, and multiplexing functions previously handled by multiple chips. It serves as a successor to earlier generation encoders with improved noise filtering and motion estimation algorithms.

Encoders, Decoders, Converters Replacement Considerations

The SAA6752HS/V103 is documented as a replacement for the SAA6752HS/V101 with enhanced functionality. For applications not requiring AC-3 encoding, the SAA6752HS/V104 serves as a replacement for the SAA6752HS/V102.
