描述

Differentiating from the legacy Cirrus multi-standard, multi channel decoders, this new CS48500 family is still based on the same high-performance 32-bit fixed point DSP Digital Signal Processor core but instead is equipped with much less memory, tailoring it for more cost-effective applications associated with multi-channel and virtual-channel sound enhancements.FEATURES
❐ Cost-effective, High-performance 32-bit DSP
   — 300,000,000 MAC/S (multiply accumulates per second)
   — Dual MAC cycles per clock
   — 72-bit accumulators are the most accurate in the industry
   — 24k x 32 SRAM, 2k blocks - assignable to data or program
   — Internal ROM contains a variety of configurable sound enhancement feature sets
   — 8-channel internal DMA
   — Internal watch-dog DSP lock-up prevention
❐ DSP Tool Set w/ Private Keys for Protecting Customer IP
❐ Configurable Serial Audio Inputs/Outputs
   — Configurable for all input/output types
   — Maximum 32-bit @ 192 kHz
   — Supports 32-bit audio sample I/O between DSP chips
   — TDM input modes (multiple channels on same line)
   — 192 kHz SPDIF transmitter
   — Multi-channel DSD direct stream digital SACD input
❐ Supports Two Different Input Fs Sample Rates
   — Output can be master or slave
   — Dual processing path capability
   — Input supports dual domain slave clocking
   — Hardware assist time sampling for sample rate conversion
❐ Integrated Clock Manager/PLL
   — Can operate from external crystal, external oscillator
❐ Input Fs Auto Detection
❐ Host & Boot via Serial Interface
❐ Configurable GPIOs and External Interrupt Input
❐ 1.8V Core / 3.3V I/O that are +5V Tolerant
❐ Low-power Mode
   — "Energy-Star Ready" via low-power mode, 350uW in standby
