Tripath Technology, Inc. – Preliminary Technical Information TCD6000 6 CHANNEL CLASS-T DIGITAL AUDIO PROCESSOR USING DIGITAL POWER PROCESSINGTM TECHNOLOGY Technical Information – Preliminary Revision 1.0 – September 2004 General Description The TCD6000 is a high-performance 6-channel digital audio amplifier processor. It receives 6 digital audio channels (3 pairs) and outputs 6 complementary single-bit digital data streams suitable for driving Tripath or other switching output stages. The TCD6000 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 TCD6000 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) 104dB dynamic range THD+N less than 0.03% Input sampling rates up to 192kHz I2C compatible interface Stereo headphone amplifier Predictive Gain Control Digital volume control 128dB range 1/2 dB step size in 1/8 dB increments Zero crossing detection for click free transitions Optional mute mode leaves headphone amplifiers operating Automatic DC offset cancellation 130uV noise floor (PGC = 1/8, low post gain) Digital de-emphasis filtering for 32, 44.1 and 48kHz sampling ra……
