The WT3080 is a dedicated vocoder chip independently developed by Nanjing Indigo Microelectronics for DMR digital radio applications, featuring built-in AMBE+2 vocoder software compliant with the DMR protocol recommendations. DMR digital radios designed based on the WT3080 chip can effectively interoperate with Motorola DMR systems. The WT3080 adopts a new integrated circuit manufacturing process, which effectively reduces product cost, PCB area, and operating power consumption; the chip requires a simple external circuit, and the MCU can operate it simply through a UART interface, greatly facilitating the application design of handheld terminals. ■ Algorithm: AMBE+2 ■ Encoding Rate: Compatible with AMBE3000 ▪ Default: 2450bps voice + 1150bps FEC ■ MCU Interface: UART, packet mode protocol, user-configurable baud rate ■ Operating Voltage: IO 3.3V, Core 1.8V ■ Power Consumption: ≤150mW ■ QFN64 Package: 8.00mm × 8.00mm × 0.85mm Application Scenarios: DMR, dPMR |
