Description
The CXA1124AS is an original vintage bipolar silicon monolithic integrated circuit (IC) manufactured by Sony Corporation. Housed in a large 42-pin Shrink Dual In-Line Package (SDIP/DIP-42), this highly complex, specialized component serves as a comprehensive, single-chip US Audio Multiplexing Decoder designed for television Multi-channel Television Sound (MTS) systems.
Key Features & Specifications:
- Core Function: All-in-one television MTS Stereo and SAP (Second Audio Program) Demodulator.
- Integrated Technology: Features an onboard licensed dbx-TV noise reduction decoder module alongside active filtering techniques that heavily minimize the need for external processing circuits.
- Advanced Calibration: Utilizes an internal, adjustment-free pilot cancel circuit and a quasi-sine wave stereo demodulator matrix to maximize channel separation and reduce distortion.
- Package Type: 42-Pin Plastic DIP / SDIP (Through-Hole).
- Applications & Sourcing Crosses: Extensively deployed as the master audio processing engine within classic high-end CRT television mainboards, legacy VCR decks, and projection systems from the late 1980s and early 1990s (including original configurations by Sanyo, Fisher, LXI, and Sony Trinitron chassis).
- Manufacturer: Sony Corporation (Japan)
An authentic, rare New-Old-Stock (NOS) structural replacement semiconductor. Essential for bench audio-video technicians, retro gaming enthusiasts, and vintage television preservationists looking to restore dropped or buzzing stereo channels, failing SAP sub-carrier operations, or total analog sound multiplex decoding failures.
