Line-level analog audio outputs routed to the primary audio power amplifier circuit. 4. System Control and Interfaces
Handles volume, balance, bass, treble, and spatial audio effects (such as pseudo-surround sound).
Acts as a master/slave controller to communicate with external EEPROMs, tuners, and peripheral ICs. 2. Key Specifications and Absolute Maximum Ratings vct49x3f py f1000 datasheet

The VCT49X3F PY F1000 is a highly integrated, single-chip video and audio processor designed by Micronas (now TDK-Micronas). It belongs to the renowned VCT (Video Compact Television) family. This integrated circuit (IC) was widely adopted by major television manufacturers, including Samsung, LG, and Sony, to power their cathode-ray tube (CRT) and early-generation flat-panel displays. Acts as a master/slave controller to communicate with
Since the part is long obsolete, your best options for sourcing it are:
While some supplier listings may inaccurately attribute the part to Microchip, the VCT49X3F series is originally a component.. You may also see it listed with similar codes like VCT49X3F-PZ-F1000 or VCT49X3F-PY-F1 , which are likely firmware or packaging variants for different TV brands and chassis.
Composite video inputs for standard definition signals from composite RCA jacks or tuners.
