Thin-film bulk acoustic resonators include a resonator body, a bottom electrode on the resonator body and a piezoelectric layer on the bottom electrode. The series combination provides good absorption of shock loads without exceeding suspension system packaging constraints. The frame demultiplexers convert at least one 10 gigabits Ethernet frame into a plurality of gigabit Ethernet frames. This reduces the complexity of the electronics so that the only one voltage generator is needed for the display.
