IS2083
– Up to +11 dBm (typical) for Basic Data Rate (BDR) – Up to +9.5 dBm (typical) for Enhanced Data Rate (EDR) • Integrated Medium Power Amplifier (MPA) and Low Power Amplifier (LPA)
MCU Features
• 8051 8-bit core • 8-bit data • 24-bit program counter (PC24) mode • 24-bit data pointer (DPTR24) mode • Operating speed: – DC – 48 MHz clock input – 0.33-1 MIPS/MHz, depending on instruction
DSP Voice and Audio Processing
• 16/32-bit DSP core with enhanced 32-bit precision, single cycle multiplier • Synchronous Connection-Oriented (SCO) channel operation • Modified Sub-Band Coding (mSBC) decoder for wideband speech • Built-in High-definition Clean Audio (HCA) algorithms for both narrowband and wideband speech processing • Built-in audio effect algorithms to enhance audio streaming • 64 Kbps A-Law, μ-Law Pulse Code Modulation (PCM), or Continuous Variable Slope Delta (CVSD) modulation for SCO channel operation • 8/16 kHz Noise Reduction (NR) • 8/16 kHz Acoustic Echo Cancellation (AEC) • Packet Loss Concealment (PLC) for SBC and mSBC codecs only
Audio Codec
