# AH86G11-VC1
__16-in/16-out TDM256 Slave 48kHz / 24bit·32bit USB Multi-channel Digital Audio Interface__
</div>
</div>
## 1. Introduction
### 1.1 Product Description
AH86G11 is a **USB multi-channel digital audio interface core module** based on the xcore.ai (XMOS) multi-core architecture, designed for audio front-end applications that interconnect with an external DSP in digital mixing consoles / multi-channel mixing systems. AH86G11 connects to a host (PC / Mac) via a **USB Audio Interface (UAC)**, and externally provides a **16-channel input / 16-channel output** TDM digital audio interface to interconnect with a DSP. It adopts the **TDM256 frame format (8 channels per data line)**, implementing 16-in / 16-out through 2 input data lines and 2 output data lines.
AH86G11 operates in Slave mode with a fixed sampling rate of 48kHz, and supports 24bit / 32bit audio data bit depths: USB supports 48K 24bit/32bit, while TDM supports only 32bit. The clock is **provided by the external DSP**: the DSP outputs the bit clock `BCLK` (`I2S0_SCLK`) and the frame sync `FS` (`I2S0_LRCLK`) to AH86G11, and AH86G11 operates as a clock slave.
<!-- !!! info "Clock Relationship"
At 48kHz / TDM256 configuration, each frame is 256 bit, and each data line carries 8 × 32bit channels.
- `FS` (LRCLK) = 48kHz
- `BCLK` (SCLK) = 48kHz × 256 = **12.288MHz**
- Each TDM256 data line = 8 channels; 2 input lines = 16-in, 2 output lines = 16-out
- `MCLK`: Optional; if the DSP does not provide MCLK separately, the user may connect AH86G11's MCLK to BCLK (MCLK = BCLK = 12.288MHz) -->
### 1.2 Product Features
**Audio Interface Features**
- **USB Audio Interface (UAC)**: Multi-channel USB audio interface connecting to a host (PC / Mac), 48kHz / 24bit·32bit
- **TDM256 Multi-channel Interface**: 16-in / 16-out, 2 TDM256 input data lines (16 channels) + 2 TDM256 output data lines (16 channels), 8 channels per data line
- **Sampling Rate**: Fixed 48kHz
- **Bit Depth**: USB supports 24bit / 32bit; TDM supports only 32bit
**Clock Features**
- **Slave Mode**: The clock is provided by the external DSP; the DSP outputs the bit clock `BCLK` (`I2S0_SCLK`) and the frame sync `FS` (`I2S0_LRCLK`), and AH86G11 operates as a clock slave
- Only 2 external clock lines: `BCLK` + `FS`
- `MCLK`: The DSP may not provide it separately; if not provided, the user may connect MCLK to BCLK (MCLK = BCLK)
### 1.3 Application Scenarios
- Digital Mixer — multi-channel audio front-end for mixing consoles, forms a mixing / effects processing chain with an external DSP, 16-in / 16-out channel routing
- Multichannel Audio Router — channel-level digital audio distribution, TDM multi-channel interconnection, signal aggregation for recording / PA systems
- Conference / PA System — multi-microphone channel aggregation, audio interface interfacing with the system DSP, fixed 48kHz engineering audio applications
