WebNov 28, 2011 · I'm thinking about a clock selector board that has two clocks 22.5792Mhz and 24.576Mhz, a clock divider with 74VHC393 and PCM clock speeds selectable for /1 /2 /4 /8 (through a BCD to decimal and some AND gates). For this to work the RPi should specify the division factor and the frequency domain used 44.1k or 48k multiplies. WebIn electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. The selection is directed by a separate set of digital inputs known as select lines. A multiplexer of inputs has select lines, which are … john d williamson photography
