SCT2088: Narrow Band Multi-way radio chip

Overview

The SCT2088 is a low power high performance baseband processor supporting Full-duplex and Multi-way radio protocol. With an internal codec (audio band ADC and DAC), it completes the data link layer, and most of the call control layer processing.

Features

• Full-duplex Intercom Protocol
• Ultra-low latency
• Multi-way Intercom Protocol
• Supports up to 6 people full duplex intercom
• No limited listeners number
• Configurable channels
• Low latency
• Audio Processing
• Noise Suppression(NS)
• Acoustic Echo Cancellation(AEC)
• Voice Activity Detection(VAD)
• Audio Automatic Gain Control(Audio AGC)
• Codec
• Two channel 24-bit sigma-delta ADC and DAC.
• Audio PLL.
• Two pairs differential input and 2 single-ended inputs.
• Two pairs of line outputs
• Programmable analog and digital gain
