Introduction
TAS5548 is an 8-channel digital PWM modulator with digital audio processing and a sample rate converter, offering advanced performance and high system integration. The TAS5548 is designed to support DTS-HD specification Blu-ray HTiB applications. The ASRC contains two independent modules, each capable of processing 4 channels, enabling support for up to two different input sample rates. The power stage is designed to work seamlessly with the TAS5548. The TAS5548 also provides a high-performance, differential output to drive an external, differential-input, analog headphone amplifier. For 48, 96, and 192kHz data, the TAS5548 supports AD, BD, and tri-state modulation at a switching rate of 384kHz. An external crystal oscillator at 12.288MHz is required. The TAS5548 also features Power Supply Volume Control (PSVC), which increases the dynamic range of low-power stages and can serve as part of a Class G power supply when used with closed-loop PWM input power stages.
Features
- 8-channel asynchronous sample rate converter
- 8-channel audio processing at 32–192kHz (ASRC up to 96kHz)
- 4-channel native audio processing at 192kHz
- 30kHz audio bandwidth for DTS-HD compatibility
- Energy manager for overall system power control
- Power supply volume control
- Up to 5 synchronous serial audio inputs (10 channels)
- Up to 1 synchronous serial audio output (2 channels)
- I2S master mode when used with external crystal oscillator
- Controlled mode 32–192kHz with auto/manual sample rate detection
- 8 differential PWM outputs supporting AD or BD modulation
- Two differential PWM headphone outputs
- I2S support for external wireless sub PWM output, single-ended (S.E.) or bridge-tied load (BTL)
- Volume control range: 18dB to −127dB (master and 8-channel volume)
- Bass and treble tone control with ±18dB range and selectable corner frequency
- Configurable loudness compensation
- Two dynamic range compressors with two thresholds, two offsets, and three slopes
- Seven second-order IIR biquad filters per channel
- Dynamic range >105dB
- THD+N <0.1% (0–40kHz)
- 20Hz–40kHz white noise reference for 32kHz–192kHz
- Flexible auto logic with programmable threshold and noise-free operation duration
- Power supply volume control (PSVC) for high-performance applications
- Adjustable modulation limit
Applications
- Seamless compatibility with most digital audio decoders
