![]() In this post, we want to implement the complementary interface of the parallel to serial interface. Many FPGA vendors like Xilinx, Intel/Altera give us the possibility to use internal serializer-deserializer such as a serial transceiver. This approach is very useful in interfacing different devices. WLAN 802.11ac 802.In this post, we analyzed the VHDL code for a parallel to serial converter. D Flipflop T Flipflop Read Write RAM 4X1 MUX 4 bit binary counter Radix4 Butterfly 16QAM Modulation 2bit Parallel to serial RF and Wireless tutorials Refer following as well as links mentioned on left side panel for useful VHDL codes. Information to be converted to analog format for transmission.ĭAC FPGA VHDL/VERILOG code for the same can be easily written. In DAC FPGA interface, SYNC is pulled HIGH and then 16 bits are being written.įirst 2 bits are zeroes, next 2 bits are configuration bits and rest 12 bits are actual ![]() ADC FPGA VHDL/VERILOG code for the same can be easily written. The 12 bit represents voltage acquired by the ADC. In ADC FPGA interface, CS is pulled low and then four zeroes are being transmitted which isįollowed by 12 bits. Both ADC and DAC are 12 bit analog to digital converter andġ2 bit digital to analog converters respectively. The figure-3 depicts ADC and DAC serial data interface timing diagram obtained fromĭatasheets of the ADC/DAC.
