This product has been discontinued, click here for discontinuation information and replacement parts.

Features and benefits

  • Low power consumption

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

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

  • Choice of three phase comparators:

    • PC1: EXCLUSIVE-OR

    • PC2: Edge-triggered J-K flip-flop

    • PC3: Edge-triggered RS flip-flop

  • Excellent Voltage Controlled Oscillator (VCO) linearity

  • 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: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

Applications

  • FM modulation and demodulation

  • Frequency synthesis and multiplication

  • Frequency discrimination

  • Tone decoding

  • Data synchronization and conditioning

  • Voltage-to-frequency conversion

  • Motor-speed control

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
