CD4046B CMOS Micropower Phase-Locked Loop (PLL) consists of a low-power, linear voltage-controlled oscillator (VCO) and two different phase comparators having a common signal-input amplifier and a common comparator input. A 5.2-V zener diode is provided for supply regulation if necessary.


  • Very low power consumption: 70 µW (typ.) at VCO fo = 10 kHz, VDD = 5 V
  • Operating frequency range up to 1.4 MHz (typ.) at VDD = 10 V, RI = 5 k
  • Low frequency drift: 0.04%/°C (typ.) at VDD = 10 V
  • Choice of two phase comparators:
    • Exclusive-OR network (I)
    • Edge-controlled memory network with phase-pulse output for lock indication (II)
  • High VCO linearity: <1% (typ.) at VDD = 10 V
  • VCO inhibit control for ON-OFF keying and ultra-low standby power consumption
  • Source-follower output of VCO control input (Demod. output)
  • Zener diode to assist supply regulation
  • Standardized, symmetrical output characteristics
  • 100% tested for quiescent current at 20 V
  • 5-V, 10-V, and 15-V parametric ratings
  • Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of 'B' Series CMOS Devices"


  • FM demodulator and modulator
  • Frequency synthesis and multiplication
  • Frequency discriminator
  • Data synchronization
  • Voltage-to-frequency conversion
  • Tone decoding
  • FSK - Modems
  • Signal conditioning
  • (See ICAN-6101) "RCA COS/MOS Phase-Locked Loop - A Versatile Building Block for Micropower Digital and Analog Applications"
