CD 서보 및 압축 오디오 디코더 IC: TC94A92FG / TC94A93MFG

The TC94A92FG and TC94A93MFG audio playback processors support both CD and compressed audio formats. The TC94A93MFG contains a 16-Mbit DRAM in a system-in-package (SiP) to provide shockproof capability necessary for car audio applications. The TC94A92FG and TC94A93MFG are pin-compatible and interchangeable with each other. This makes it possible to use the same pc board to create CD/MP3 players with and without shockproof capability. Additionally, the TC94A92FG and TC94A93MFG can take audio bit streams from USB memory sticks and portable music players like iPod. These CD/MP3 processors can be configured to support a variety of media according to your product specification.
