DIGITAL DATA RECEIVER

摘要: PURPOSE: To realize low power consumption by using a clock generated from temperature compensation crystal oscillator (TCXO) used for the receiver transmission red generative circuit and CPU of demodulator, operating TCXO even during intermittent non-reception to hold synchronization with high accuracy an exclusive use only at start operation. CONSTITUTION: A capacitor 8, inverter 9 feedback resistor frequency divider 10 are provided between 5 regenerative signal 4 is 7. Furthermore, switch 15 select 26 oscillation 14 or 25 usual operation allow 11 state that stopped.
