Features  
Description  
• Center Frequency of 18MHz (Typ) at V  
Minimum Center Frequency of 12MHz at V  
= 5V,  
The CD74HC7046A and CD74HCT7046A high-speed  
silicon-gate CMOS devices, specified in compliance with  
JEDEC Standard No. 7A, are phase-locked-loop (PLL)  
circuits that contain a linear voltage-controlled oscillator  
(VCO), two-phase comparators (PC1, PC2), and a lock  
detector. A signal input and a comparator input are common  
to each comparator. The lock detector gives a HIGH level at  
pin 1 (LD) when the PLL is locked. The lock detector

capacitor must be connected between pin 15 (C ) and pin

8 (Gnd). For a frequency range of 100kHz to 10MHz, the  
lock detector capacitor should be 1000pF to 10pF,  
respectively.  
• Minimal Frequency Drift

• Zero Voltage Offset Due to Op-Amp Buffer  
ject  
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 low-pass filter, the 7046A forms a second-  
order loop PLL. The excellent VCO linearity is achieved by  
the use of linear op-amp techniques.
