The 900 MHz signal is generated by a standard synthesizer (LMX2332) and VCO combination. The output is filtered to reduce harmonics. 2. Video board for driving cable tv onto an LCD screen 3. CD control board to control a front-loading CD player 4. Tape control board to manage a full logic cassette mechanism 5. A control board consisting of several micro’s and an audio processor with a DSP and CODEC. The block diagram is shown on the next page. e-zone07/16/01 Research & DevelopmentTodd Simpson V.P.
