发明名称 Intermittent operation receiver with variable pre-heat time for its phase-locked circuit
摘要 An intermittent operation receiver e.g. a pager, comprises a receiving circuit (8) receiving one of plural intermittent receiving operation information and data transmitted from a base station and generating its demodulated signal (24), a PLL circuit (7) including a voltage-controlled oscillator (5) and supplying two signals (25, 26) in phase quadrature to the receiving circuit (8) to process the input signal, and a data processing section (14) decodes the data to provide a first intermittent cycle generation timing signal (18) to the receiving circuit (8) to control the power supply from its power source unit. Meanwhile, data processing section (14) selectively determines a pre-heat or stabilization time (t1, or t2, or t3) in accordance with the designated intermittent operating cycle, a second intermittent cycle generation timing signal to the PLL circuit (7) to control the power supply from its power source unit. The processing section 14 may include a timing setting section 36 for determining the pre-heat time in dependence upon information received from a base station or from a ROM 15.
