Uart With Auto Tuning Baud Rate Generator
The baud rate used by the PC 2 is selected from a standard range of rates, which in this example are 4,800, 9,600, 19,200, 57,600, 115,200 and 230,400 Hz and the auto-detect component 9 configures the i/o circuit 22 to sample the data line 8 at twice the maximum. To improve the reusability and flexibility of the UART IP core, an auto-tuning baud rate generator is designed to replace the baud rate generator module. Jan 24, 2020 Each UART of the V354 s many enhanced features such as the 256-bytes TX and RX FIFOs, programmable Fractional Baud Rate Generator, Automatic Hardware or Software Flow Control, Auto RS-485 Half-Duplex Direction Control, programmable TX and RX FIFO Trigger Levels, TX and RX FIFO Level Counters, infrared mode, and data rates up to 25 Mbps. 2PCS 433M RS485 Wireless Transceiver Module DTU UART RS232 485 422 RF Smart Home. Item Information. 2PCS 433M RS485 Wireless Transceiver Module DTU UART RS232 485 422 RF Smart Home. It is flexible for the users to set the UART baud rate, frequency, output power, data rate, frequency deviation, receiving bandwidth etc parameters.
- The V1412 operates from an internal 48MHz clock therefore no external crystal/oscillator is required like previous generation UARTs. With the fractional baud rate generator, any baud rate can accurately be generated using the internal 48 MHz clock. The V1412 operates from a single 2.97 to 3.63 volt power supply and has 5 V tolerant inputs.
- This paper describe the UART IP core based DMA has been proposed. This technique has high flexibility and less consume time of CPU that the performance of embedded system is high. The baud rate generator and auto-tuning approach in UART IP core based are simple and flexible, which can be applied to other application designs as a separate core.

It requires an external decoupling capacitor to be attached to the 3V3OUT regulator output pin. USB Transceiver The USB Transceiver Cell provides the USB 1.1 full-speed physical interface to the USB cable. The output drivers provide 3.3 volt level slew rate control signalling, whilst a differential receiver and two single ended receivers provide USB data in, SEO and USB Reset condition detection. USB DPLL The USB DPLL cell locks on to the incoming NRZI USB data and provides separate recovered clock and data signals to the SIE block. 6MHz Oscillator The 6MHz Oscillator cell generates a 6MHz reference clock input to the X8 Clock multiplier from an external 6MHz crystal or ceramic resonator. X8 Clock Multiplier The X8 Clock Multiplier takes the 6MHz input from the Oscillator cell and generates a 12MHz reference clock for the SIE, USB Protocol Engine and UART FIFO controller blocks. It also generates a 48MHz reference clock for the USB DPPL and the Baud Rate Generator blocks. Serial Interface Engine ( SIE ) The Serial Interface Engine ( SIE ) block performs the Parallel to Serial and Serial to Parallel conversion of the USB data. In accordance to the USB 1.1 specification, it performs bit stuffing / un-stuffing and / CRC16 generation / checking on the USB data stream. USB Protocol Engine The USB Protocol Engine manages the data stream from the device USB control endpoint. It handles the low level USB protocol ( Chapter 9 ) requests generated by the USB host controller and the commands for controlling the functional parameters of the UART. Dual Port TX Buffer ( 128 bytes ) Data from the USB data out endpoint is stored in the Dual Port TX buffer and removed from the buffer to the UART transmit register under control of the UART FIFO controller. |
