Features

  • 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
  • Low frequency drift with supply voltage and temperature variations
  • Operating power supply voltage range:
    • VCO section 3.0 V to 6.0 V
    • Digital section 2.0 V to 6.0 V
  • Zero voltage offset due to operational amplifier buffering
  • ESD protection:
    • HBM JESD22-A114F exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V

Target applications

  • FM modulation and demodulation
  • Frequency synthesis and multiplication
  • Frequency discrimination
  • Tone decoding
  • Data synchronization and conditioning
  • Voltage-to-frequency conversion
  • Motor-speed control
