Asahi Kasei Microdevices AK7017 HiFi 4 DSP/SRCs
Asahi Kasei Microdevices AK7017 HiFi 4 Digital Signal Processor (DSP)/Sampling Rate Converters (SRCs) is highly integrated. This 100-pin HLQFP packaged device includes eight stereo and four monaural SRCs supporting sampling frequencies up to 192kHz, a DIR, a DIT, and a DSP for audio and voice processing. The DSP1 supports a 491.52MHz operation clock and is optimized for C-language support. The automotive-grade Asahi Kasei Microdevices AK7017 is a RAM-based DSP1 that can be freely programmed for user requirements, such as acoustic effects.Features
