DESCRIPTION
The SN74LV4046A is a high-speed silicon-gate CMOS device that is pin compatible with the CD4046B and the
CD74HC4046. The device is specified in compliance with JEDEC Std 7.
The SN74LV4046A is a phase-locked-loop circuit that contains a linear voltage-controlled oscillator (VCO) and
three different phase comparators (PC1, PC2, and PC3). A signal input and a comparator input are common to
each comparator.
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 SN74LV4046A forms a second-order loop PLL. The excellent VCO
linearity is achieved by the use of linear operational amplifier techniques.
