The device is specified in compliance with JEDEC Std 7. The SN74LV4046A is a phase-locked loop (PLL) circuit that contains a linear voltage-controlled oscillator (VCO) and three different phase comparators (PC1, PC2, and PC3) as explained in the Features section. A signal input and a comparator input are common to each comparator as shown in the Functional Block Diagram. The signal input can be directly coupled to large voltage signals, or indirectly coupled (with a series capacitor) to small voltage signals. A self-bias input circuit keeps small voltage signals within the linear region of the input amplifiers. With a passive lowpass filter, the SN74LV4046A forms a second-order loop PLL. The excellent VCO linearity is achieved by the use of linear operational amplifier techniques. Various applications include telecommunications, Digital Phase Locked Loop and Signal generators. The VCO requires one external capacitor C1 (between C1A and C1B) and one external resistor R1 (between R1 and GND) or two external resistors R1 and R2 (between R1 and GND, and R2 and GND). Resistor R1 and capacitor C1 determine the frequency range of the VCO. Resistor R2 enables the VCO to have a frequency offset if required. The high input impedance of the VCO simplifies the design of lowpass filters by giving the designer a wide choice of resistor or capacitor ranges. In order to not load the lowpass filter, a demodulator output of the VCO input voltage is provided at pin 10 (DEMOUT). In contrast to conventional techniques where the DEMOUT voltage is one threshold voltage lower than the VCO input voltage, here the DEMOUT voltage equals that of the VCO input. If DEMOUT is used, a load resistor (RS) should be connected from DEMOUT to GND; if unused, DEMOUT should be left open. The VCO output (VCOOUT) can be connected directly to the comparator input (COMPIN), or connected through a frequency divider. The VCO output signal has a specified duty factor of 50%. A LOW level at the inhibit input (INH) enables the VCO and demodulator, while a HIGH level turns both off to minimize standby power consumption. 7.2 Functional Block Diagram VCC 16 Phase Comparator 1 2 13 PC2OUT 3 Phase Comparator 2 15 PC3OUT VCOIN 9 Phase Comparator 3 INH 5 SIGIN 14 COMPIN C1A 6 C1B 7 1 4 Voltage Controlled Oscillator PC1OUT PCPOUT VCOOUT 10 DEMOUT R1 11 R2 12 8 GND 10 Submit Documentation Feedback Copyright © 2006–2016, Texas Instruments Incorporated Product Folder Links: SN74LV4046A SN74LV4046A www.ti.com SCES656E – FEBRUARY 2006 – REVISED NOVEMBER 2016 7.3 Feature Description There are three choices for the Phase Comparators in this device which are listed as follows: • Phase comparator 1 (PC1) is an Exclusive OR network. The average output voltage from PC1, fed to VCO input through the low pass filter and seen at the demodulator output at pin 10 (VDEMOUT), is the resultant of the phase differences of signals (SIGIN) and the compartor input (COMPIN) as shown in Figure 7. The average of V DEM is equal to 1/2 VCC when there is no signal or noise at SIGIN, and with this input the VCO oscillates at the center frequency (fo). • Phase comparator 2 (PC2) is an Edge-Triggered Flip-Flop. This is a positive edge-triggered phase and frequency detector. When the PLL is using this comparator, the loop is controlled by positive signal transitions and the duty factors of SIGIN and COMPIN are not important. PC2 comprises two D-type flip-flops, controlgating and a three-state output stage. The circuit functions as an up-down counter where SIGIN causes an upcount and COMPIN a down-count. The average output voltage from PC2, fed to the VCO through the lowpass filter and seen at the demodulator output at pin 10 (VDEMOUT), is the resultant of the phase differences of SIGIN and COMPINas in Figure 8. • Phase comparator 3 (PC3) is an positive Edge-Triggered RS Flip-Flop. This is a positive edge-triggered sequential phase detector using an RS-type flip-flop. When the PLL is using this comparator, the loop is controlled by positive signal transitions and the duty factors of SIGIN and COMPIN are not important. The average output from PC3, fed to the VCO through the lowpass filter and seen at the demodulator at pin 10 (VDEMOUT), is the resultant of the phase differences of SIGIN and COMPIN as shown in Figure 9. The excellent VCO linearity is achieved by the use of linear operational amplifier techniques. It has low standby power consumption using VCO inhibit control. Wide operating temperature range from –40°C to +125°C along with an optimized power supply voltage range from 3 V to 5.5 V. 7.4 Device Functional Modes The SN74LV4046A device does not feature any special functional modes.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The most common use for the digital phased-locked loop (PLL) device is to match the VCO output to the same phase as the incoming signal and produce an error signal (DEMOUT) that indicates the amount of phase shift required for the match. This can be used as part of many complex systems. 8.2 Typical Application VCC 16 SIGIN Input COMPIN VCOOUT INH C1A C1 C1B R1 R2 R1 R2 14 3 4 Phase Comparator 1 2 Phase Comparator 2 13 Phase Comparator 3 5 6 7 1 15 9 Voltage Controlled Oscillator 10 PC1OUT PC2OUT R3 PCPOUT C2 PC3OUT VCOIN DEMOUT R5 11 12 8 GND Figure 9.

Each VCC pin should have a good bypass capacitor to prevent power disturbance. For devices with a single supply. a 0.1-µF capacitor is recommended and if there are multiple VCC pins then 0.01-µF or 0.022-µF capacitor is recommended for each power pin. It is ok to parallel multiple bypass capacitors to reject different frequencies of noise. 0.1-µF and 1-µF capacitors are commonly used in parallel. The bypass capacitor should be installed as close to the power pin as possible for best results. 10 Layout 10.1 Layout Guidelines Reflections and matching are closely related to the loop antenna theory but are different enough to be discussed separately from the theory. When a PCB trace turns a corner at a 90° angle, a reflection can occur. A reflection occurs primarily because of the change of width of the trace. At the apex of the turn, the trace width increases to 1.414 times the width. This increase upsets the transmission-line characteristics, especially the distributed capacitance and self–inductance of the trace which results in the reflection. Not all PCB traces can be straight and therefore some traces must turn corners. Figure 10 shows progressively better techniques of rounding corners. Only the last example (BEST) maintains constant trace width and minimizes reflections. 10.2 Layout Example BETTER BEST 2W WORST 1W min. W Figure 10.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
