I am working on a baseband bit-by-bit multiplexing system recently, in which the demultiplexing part involves clock extraction and frame synchronization extraction. I will upload it now to discuss with you. Frame synchronization extraction design based on cpld (VHDL)
Today I saw a chip CD4504, which is a TTL to COMS level chip. TI's chip is marked as CM504B, and the chip CD4051B I bought is marked as CM051B. It seems that CD4 has been replaced by CM. Haha, I almos
The imbalance between supply and demand in the global MCU market has become increasingly serious recently. After foreign MCU manufacturers successively announced price increase notices, domestic MCU m
The voltage following circuit of the op amp, as shown in Figure 1, uses virtual short and virtual open circuits. It looks simple and clear at first glance, and there is not much to pay attention to. T
