74HCT9046AD

PLL with band gap controlled VCO

The 74HCT9046A. This device features reduced input threshold levels to allow interfacing to TTL logic levels. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features and benefits

  • Operation power supply voltage range from 4.5 V to 5.5 V

  • Low power consumption

  • Complies with JEDEC standard no. 7A

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

  • Center frequency up to 17 MHz (typical) at VCC = 5.5 V

  • Choice of two phase comparators:

    • PC1: EXCLUSIVE-OR

    • PC2: Edge-triggered JK flip-flop

  • No dead zone of PC2

  • Charge pump output on PC2, whose current is set by an external resistor Rbias

  • Center frequency tolerance ±10 %

  • Excellent Voltage Controlled Oscillator (VCO) linearity

  • Low frequency drift with supply voltage and temperature variations

  • On-chip band gap reference

  • Glitch free operation of VCO, even at very low frequencies

  • Zero voltage offset due to operational amplifier buffering

  • ESD protection:

    • HBM JESD22-A114F exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V

Applications

  • FM modulation and demodulation where a small center frequency tolerance is essential

  • Frequency synthesis and multiplication where a low jitter is required (e.g. video picture-in-picture)

  • 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.
