Information Using Evaluation Board
Power Supply Supply power evaluation board attached power cord. brown wires +5V, black wire ground, green wire -5V. Switches Terminals used open/close signals such SLS11, SLS21, SLS12, SLS22, RXSEL, RCW1, AFC1, RPR1, RCW2, AFC2, RPR2, PDN2, PDN1, PDN0 switches S1-S14. With terminals closed, signal asserted negated control switches S14. With terminals open, control signals entered through pins 40-pin flat cable connector. Terminals used connect IFCK with MSM7583. During use, this terminal must closed. Terminal used control input MSM7583. this terminal follows, depending whether oscillating circuit MSM7583 used.

With operational amplifier used, output signals MSM7583 given directly terminals board. With operational amplifier used, addition output terminal, addition buffered output terminal.
Semiconductor Crystal Oscillator
MSM7583
MSM7583 uses crystal oscillator depending input signal frequency. following frequencies used:
signal frequency 1.2MHz/10.8MHz 10.7MHz 10.75MHz
Frequency crystal oscillator used 19.0222MHz 19.1111MHz
Operational Amplifier operational amplifier inserted into 8-pin socket marked with must have following assignment.
Setting MSM7583 Serial Control Register Turning switch push button serial control register allows load MSM7583 with data switches contents registers, data sheets. Other Signals signals (modulating wave inputs) entered through terminals IFIN1 IFIN2 board. TXCI, (send clock, send data send data window) entered through pins 40-pin flat cable connector. External control signals entered signals output through 40-pin flat cable connector. relationships between signals connector pins, separate circuit diagram.
