Description

TC94A70FG and TC94A73MFG are highly

integrated, high-performance CD-MP3

solutions that enable playback of CD and

multiple compressed audio formats from a

single chip. Featuring high-quality audio

output in I2S, S/PDIF or analog stereo

formats, the TC94A70FG integrates an RF

amplifier, CD servo, audio DSP, 1 Mbit

SRAM, and a multi-bit DA converter in a

CMOS monolithic IC. To the TC94A70FG

feature set, the TC94A73MFG adds

electronic shock protection (ESP) with

DSP firmware and 16 Mbit DRAM in an

SiP solution. TC94A70FG and

TC94A73MFG are available in standard

ROM versions or can also be customized

to specific customer requirements using

an extensive and growing DSP firmware

library including MP3, WMA, ATRAC CD,

AAC, graphic equalization and popular

surround sound formats. Pin compatibility

between the monolithic TC94A70FG and

the SiP TC94A73MFG minimizes the

engineering investment needed to upgrade

TC94A70FG CD playback designs with ESP.

New product design is further aided by

programmable RAM and macro commands

that simplify CD mechanism playback and

compressed audio tag and file management.

High integration, software customization, and

pin-compatible packages make TC94A70FG

and TC94A73MFG ideal for compressed

audio CD players where low cost, feature

flexibility and time to market are key

selection criteria.
