Introduction

TAS5558 is an 8-channel digital PWM modulator with digital audio processing and a sample rate converter, offering advanced performance and high system integration. The TAS5558 is designed to support DTS-HD specification Blu-ray HTiB applications. The ASRC contains two independent modules, each capable of processing 4 channels, thus supporting up to two different input sample rates. The power stage is designed to work seamlessly with the TAS5558. The TAS5558 also provides a high-performance, differential output to drive an external, differential-input, analog headphone amplifier. For 48, 96, and 192kHz data, the TAS5558 supports AD, BD, and ternary modulation at a switching rate of 384kHz. An external crystal oscillator at 12.288MHz is required. The TAS5558 also features Power Supply Volume Control (PSVC) to increase the dynamic range at low power levels, and when used with a closed-loop PWM input power stage, can serve as part of a Class G power supply.
