Hardware Design Reference¶
Chipintelli provides a variety of scheme reference schematics, which can meet most common application scenarios. In the actual application development, the customer needs to carefully select one of the most suitable reference schematics for reference and design optimization according to the specific product functional performance requirements, system characteristics and application scenarios. As Chipintelli is unable to master all product systems and application knowledge, customers or solution partners are expected to fully test and verify product functional performance (including the matching of voice chips and modules with product systems) in combination with product systems and application scenarios before mass production. If there are unclear and uncertain problems during the design modification process, please contact Chipintelli FAE engineer for full communication.
Reference schematic diagram of CI1301&CI1302&CI1303¶
| Scheme name | Scheme function | Scheme application scenario | Document center link |
|---|---|---|---|
| Typical scheme | Single microphone differential microphone input with echo cancellation function | Suitable for widely used products, products with broadcasting and echo cancellation | ☞Reference schematic diagram for typical scheme |
| Low power consumption scheme | 1.1V power supply is powered by external DCDC, significantly reducing power consumption | Products with high requirements for power consumption, such as products with energy consumption level restrictions | ☞Refer to the schematic diagram for low power consumption scheme |
| Highly reliable solution | Strong ESD EMC anti-interference ability, power interference resistance ability, improve product reliability | For products with poor system power quality, high product reliability requirements, products requiring FCC CE certification, and products with high requirements for ESD, please refer to the | ☞Reference Schematic Diagram for Highly Reliable Solution |
| Low cost solution | Single ended microphone, the simplest circuit without AEC application | Products with extreme cost requirements and low reliability requirements, products with microphone line length less than 20cm, such as toys and FMCG products | ☞Reference schematic diagram for low cost solution |
