Overview
The CD4046BE is a CMOS Micropower Phase-Locked Loop (PLL) produced by Texas Instruments. It is part of the CD4000 IC family and features a low-power, linear voltage-controlled oscillator (VCO) and two different phase comparators. The device includes a common signal-input amplifier and a common comparator input, making it versatile for various applications. It also includes a source follower, a Zener diode for supply regulation, and a VCO inhibit control for ON-OFF keying and ultra-low standby power consumption.
