TCD6001

Tripath Technology, Inc. – Preliminary Technical Information TCD6001 6 CHANNEL CLASS-T DIGITAL AUDIO PROCESSOR USING DIGITAL POWER PROCESSINGTM TECHNOLOGY PRELIMINARY INFORMATION Revision 0.9– July 2005 General Description The TCD6001 is a high-performance 6-channel digital audio amplifier processor. It accepts 6 digital audio channels (3 pairs), and outputs 4 complementary single-bit digital data streams, suitable for driving Tripath switching output stages. The other two channels of digital input are converted and routed to a stereo line-out stage capable of driving headphones. The TCD6001 accepts data at audio sample rates ranging from 32kHz to 192kHz and incorporates digital interpolation and sigma-delta conversion to produce streamed digital output signals. When combined with switching output stages, the TCD6001 allows the implementation of a complete digital audio system incorporating Class-T Digital Audio Amplification. Features Class-T architecture combining ultra-low distortion with high efficiency Inputs support I2S and other PCM audio formats Up to 24-bit resolution (16, 18, 20, and 24 bit) 4 channel complementary output stream capable of interfacing with various power stages 2 channel line-out / headphone drive with discrete digital input Wide dynamic range THD+N less than 0.03% Input sampling rates up to 192kHz I C compatible interface Seamless connection with Tripath TPS4070 or TPS4100 power stage Low EMI AM Mode Predictive Gain Control Digital volume control...
