Texas Instruments · Clock Generators, PLLs, Frequency Synthesizers · SOIC-16

CD74HC4046AM from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 PCPOUT output Phase Comparator Pulse Output; indicates locked condition when HIGH.
2 PC1OUT output Phase Comparator 1 Output from Exclusive-OR logic.
3 COMPIN input Comparator Input common to all three phase comparators.
4 VCOOUT output VCO Output with 50% duty factor.
5 INH input Inhibit Input; LOW enables VCO and demodulator, HIGH disables for low standby power.
6 C1A passive Capacitor C1 Connection A; connect external frequency-setting capacitor between C1A and C1B.
7 C1B passive Capacitor C1 Connection B; connect external frequency-setting capacitor between C1A and C1B.
8 GND power_in Ground (0V reference).
9 VCOIN input VCO Input control voltage; valid operating range 1.1V to VCC-0.9V.
10 DEMOUT output Demodulator Output; high impedance if unused, load with resistor RS greater than 300kΩ if used.
11 R1 passive Resistor R1 Connection; external resistor 3kΩ to 300kΩ from R1 to GND sets VCO frequency range.
12 R2 passive Resistor R2 Connection; external resistor 3kΩ to 300kΩ from R2 to GND provides frequency offset.
13 PC2OUT tri_state Phase Comparator 2 Output from edge-triggered phase and frequency detector; three-state output.
14 SIGIN input Signal Input common to all three phase comparators; DC or AC coupled operation.
15 PC3OUT output Phase Comparator 3 Output from positive edge-triggered RS flip-flop.
16 VCC power_in Positive Supply Voltage; HC types operate from 2V to 6V.
