USB HiFi Decoder Core Module Series¶
I. Core Modules Based on A316-1926-V1¶
A316-1926V1 is a USB multi-channel high-definition audio decoder module. The module uses XMOS XU316-1024-QF60BC24 chip and integrates high-precision DC-DC chips that output 1.8V and 0.9V voltages for XU316. The module integrates 45.158MHz and 49.152MHz active crystals to meet different high-definition audio sample rate requirements. The module includes the 24MHz crystal required by XU316 and 16Mbit Flash for storing audio firmware.

Key Feature Descriptions¶
Comparison Between HF87621 Series and HF87611 Series¶
- HF87621-VB1 / HF87621Q-VB1:
- 3-channel S/PDIF input, no S/PDIF output
- Retains I²S(S)→I²S(M) functionality
- Other features remain consistent with HF87611 series
Model Naming Convention¶
- With Q suffix: Supports MQA decoding (MQA replaces PEQ)
-
Without Q suffix: Provides 32-band PEQ, does not support MQA decoding
-
* Supports AES3, S/PDIF, IEC 60958, and EIAJ CP-1201 digital interface inputs, but only one input can be selected at a time.
- I²S(S): I²S in Slave mode
- I²S(M): I²S in Master mode
- The UAC2.0→I²S(M) column shows MAX IN/OUT specs; UAC1.0→I²S(M) is fixed at PCM48kHz; x = not supported
- All models in this list are in Active (mass-production) status; Qty｜Price(RMB) is based on 1Kpcs volume — contact sales for quotation
II. Core Modules Based on A316-Mini-V1¶
A316-Mini-V1 is a mini module designed for compact products, with dimensions of only 13mm×13mm. The module integrates XU316-1024-QF60BC24 chip and includes the 24MHz crystal required by XU316 and 16Mbit Flash for storing audio firmware.
