ZL38080LDG1

Overview

The ZL38080LDG1 is a hands-free automotive audio processor utilizing Microsemi AcuEdge Technology. It features a DSP with voice hardware accelerators, dual delta-sigma DACs supporting up to 48 kHz sampling, and four single-ended or two differential output amplifiers. The device includes one digital microphone interface, two TDM ports (PCM/I2S), SPI slave and master interfaces, and 14 GPIO pins. It supports AEC tail lengths up to 256 ms at 8 kHz and 16 kHz sampling rates. Single talk TCLw exceeds 60 dB, while double talk TCLw exceeds 40 dB. Noise reduction reaches up to 30 dB. The component is housed in a 64-pin QFN (9x9) package.
