产品详情

特性

  • Low power consumption

  • VCO-Inhibit control for ON/OFF keying and for low standby power consumption

  • Centre frequency of up to 17 MHz (typical) at VCC = 4.5 V

  • Choice of three phase comparators:

    • PC1: EXCLUSIVE-OR

    • PC2: Edge-triggered JK flip-flop

    • PC3: Edge-triggered RS flip-flop

  • Excellent Voltage Controlled Oscillator (VCO) frequency linearity

  • VCO-inhibit control for ON/OFF keying and for low standby power consumption
