CS48AU2 Dedicated 32-bit Audio DSP

The CS48AU2 is the industry's first cost-effective, high-performance 32-bit audio DSP that is solely dedicated to enable Audyssey Laboratories audio processing technologies for today's high-volume consumer electronic products.

• Audyssey Dynamic Volume™, Audyssey Dynamic EQ™, Audyssey EQ™ & Audyssey BassXT™
• Audyssey Dynamic Volume eliminates the need for constant volume adjustments
• Audyssey Dynamic EQ enables a reference playback experience at any desired playback level
• Audyssey EQ removes much of the distortion caused by speaker enclosures and the typical room environment producing greatly improved sound compared to similar products without correction
• Audyssey BassXT is specifically calibrated to enhance the physical bass response of each product model
• Configurable Serial Audio Inputs/Outputs
• • Maximum 32-bit @ 192 kHz
    (Note: Audyssey Laboratories algorithms support 48kHz, 44.1kHz and 32kHz)
  • Integrated 192 kHz capable S/PDIF transmitter
• Integrated Clock Manager/PLL
• • Can operate from external crystal, external oscillator
• Input Fs Auto Detection & Coefficient Loading
• Host Control & Boot via Serial Interface
• Support for Master (Self) Boot via Serial EEPROM for single Fs applications (i.e. 48kHz only via ADC input)
• Configurable GPIOs and External Interrupt Input
• 1.8V Core and a 3.3V I/O that is tolerant to 5V input
• Low-power Mode
• • "Energy-Star Ready" via low-power mode, 268 µW in standby
