Communication interface chip UART485/232

TS3USB221E Hi-Speed ​​USB 2.0 (480Mbps) 1:2 Multiplexer/Demultiplexer Switch with Single Enable

I/O expander

Karaoke microphone echo processing circuits, single chip with built-in input/output filters, A-D and D-A converters, and memory to realize time-delay system. ADM system provides low noise and low distortion delay system. (Typical value NO=-92dB, THD=0.5%). Two control modes to choose from: Simple mode uses parallel data input method, and microcomputer mode uses serial data input method. Built-in sleep mode stops the chip from working. Auto reset system.
